tx timeout and slot time are currently specified in units of HZ. On
Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this
results in the following error message.
drivers/net/hamradio/6pack.c: In function 'sixpack_open':
drivers/net/hamradio/6pack.c:71:41: error:
unsigned conversion from 'int' to 'unsigned char'
changes value from '256' to '0'
In the 6PACK protocol, tx timeout is specified in units of 10 ms and
transmitted over the wire:
https://www.linux-ax25.org/wiki/6PACK
Defining a value dependent on HZ doesn't really make sense, and
presumably comes from the (very historical) situation where HZ was
originally 100.
Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity:
mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100);
and the SIXP_TXDELAY walue is sent as a byte over the wire.

This driver isn't enabled most places because of the ISA config
dependency, but alpha still has it. And I think the 'Jensen' actually
did have an ISA slot.
However, it doesn't build cleanly, because the "Vortex bus master" code
just casts the skb->data pointer to 'int':
outl((int) (skb->data), ioaddr + Wn7_MasterAddr);
which is all kinds of broken. Even on a good old traditional PC/AT it
would be broken because the high bits will be random kernel address
bits, but presumably the hardware ignores those bits. I mean, it's ISA.
We're talking 16MB dma limits. The "good old days".
Make the build happy with this kind of craziness by using the proper
isa_virt_to_bus() handling that the full bus master code uses anyway
(the Vortex bus mastering is a limited special case).
Who knows, this might even work.

We can reproduce this issue with below steps:
1) enable WoL on the host
2) host system suspended
3) remote client send out wakeup packets
We can see that host system resume back, but can't work, such as ping failed.
After a bit digging, this issue is introduced by the commit 46f69ded988d
("net: stmmac: Use resolved link config in mac_link_up()"), which use
the finalised link parameters in mac_link_up() rather than the
parameters in mac_config().
There are two scenarios for MAC suspend/resume in STMMAC driver:
1) MAC suspend with WoL inactive, stmmac_suspend() call
phylink_mac_change() to notify phylink machine that a change in MAC
state, then .mac_link_down callback would be invoked. Further, it will
call phylink_stop() to stop the phylink instance. When MAC resume back,
firstly phylink_start() is called to start the phylink instance, then
call phylink_mac_change() which will finally trigger phylink machine to
invoke .mac_config and .mac_link_up callback. All is fine since
configuration in these two callbacks will be initialized, that means MAC
can restore the state.
2) MAC suspend with WoL active, phylink_mac_change() will put link
down, but there is no phylink_stop() to stop the phylink instance, so it
will link up again, that means .mac_config and .mac_link_up would be
invoked before system suspended. After system resume back, it will do
DMA initialization and SW reset which let MAC lost the hardware setting
(i.e MAC_Configuration register(offset 0x0) is reset). Since link is up
before system suspended, so .mac_link_up would not be invoked after
system resume back, lead to there is no chance to initialize the
configuration in .mac_link_up callback, as a result, MAC can't work any
longer.
After discussed with Russell King [1], we confirm that phylink framework
have not take WoL into consideration yet. This patch calls
phylink_suspend()/phylink_resume() functions which is newly introduced
by Russell King to fix this issue.

Joakim Zhang reports that Wake-on-Lan with the stmmac ethernet driver broke
when moving the incorrect handling of mac link state out of mac_config().
This reason this breaks is because the stmmac's WoL is handled by the MAC
rather than the PHY, and phylink doesn't cater for that scenario.
This patch adds the necessary phylink code to handle suspend/resume events
according to whether the MAC still needs a valid link or not. This is the
barest minimum for this support.

The cur_tx counter must be incremented after TACT bit of
txdesc->status was set. However, a CPU is possible to reorder
instructions and/or memory accesses between cur_tx and
txdesc->status. And then, if TX interrupt happened at such a
timing, the sh_eth_tx_free() may free the descriptor wrongly.
So, add wmb() before cur_tx++.
Otherwise NETDEV WATCHDOG timeout is possible to happen.

When removing the driver module w/o bringing an interface up before

The pdev maybe not a platform device, e.g. c_can_pci device, in this
case, calling to_platform_device() would not make sense. Also, per the
comment in drivers/net/can/c_can/c_can_ethtool.c, @bus_info should
match dev_name() string, so I am replacing this with dev_name() to fix
this issue.

The variable 'package_size' is an unsigned long, and should be printed
out using '%lu', not '%zd' (that would be for a size_t).
Yes, on many architectures (including x86-64), 'size_t' is in fact the
same type as 'long', but that's a fairly random architecture definition,
and on some platforms 'size_t' is in fact 'int' rather than 'long'.
That is the case on traditional 32-bit x86. Yes, both types are the
exact same 32-bit size, and it would all print out perfectly correctly,
but '%zd' ends up still being wrong.
And we can't make 'package_size' be a 'size_t', because we get the
actual value using efivar_entry_get() that takes a pointer to an

The strlcpy should not be used because it doesn't limit the source
length. As linus says, it's a completely useless function if you
can't implicitly trust the source string - but that is almost always
why people think they should use it! All in all the BSD function
will lead some potential bugs.
But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.
Thus, We prefer using strscpy instead of strlcpy.

If error recovery is already enabled, bnxt_timer() will periodically
check the heartbeat register and the reset counter. If we get an
error recovery async. notification from the firmware (e.g. change in
primary/secondary role), we will immediately read and update the
heartbeat register and the reset counter. If the timer for the next
health check expires soon after this, we may read the heartbeat register
again in quick succession and find that it hasn't changed. This will
trigger error recovery unintentionally.
The likelihood is small because we also reset fw_health->tmr_counter
which will reset the interval for the next health check. But the
update is not protected and bnxt_timer() can miss the update and
perform the health check without waiting for the full interval.
Fix it by only reading the heartbeat register and reset counter in
bnxt_async_event_process() if error recovery is trasitioning to the
enabled state. Also add proper memory barriers so that when enabling
for the first time, bnxt_timer() will see the tmr_counter interval and
perform the health check after the full interval has elapsed.

The current logic assumes that when the driver sends the message to the
firmware to add the VXLAN or Geneve port, the firmware will never fail
the operation. The UDP ports are always stored and are used to check
the tunnel packets in .ndo_features_check(). These tunnnel packets
will fail to offload on the transmit side if firmware fails the call to
add the UDP ports.
To fix the problem, bp->vxlan_port and bp->nge_port will only be set to
the offloaded ports when the HWRM_TUNNEL_DST_PORT_ALLOC firmware call
succeeds. When deleting a UDP port, we check that the port was
previously added successfuly first by checking the FW ID.

This implementation detail permeates into the HWRM API, requiring the

Broadcom's b53 switches have one IMP (Inband Management Port) that needs
to be programmed using its own designed register. IMP port may be
different than CPU port - especially on devices with multiple CPU ports.
For that reason it's required to explicitly note IMP port index and
check for it when choosing a register to use.
This commit fixes BCM5301x support. Those switches use CPU port 5 while
their IMP port is 8. Before this patch b53 was trying to program port 5
with B53_PORT_OVERRIDE_CTRL instead of B53_GMII_PORT_OVERRIDE_CTRL(5).
It may be possible to also replace "cpu_port" usages with
dsa_is_cpu_port() but that is out of the scope of thix BCM5301x fix.

tx_done is not used for napi_complete_done(). Thus, NAPI busy polling
mechanism by gro_flush_timeout and napi_defer_hard_irqs will not able
be triggered after a packet is transmitted when there is no receive
packet.
Fix this by taking the maximum value between tx_done and rx_done as
overall budget completed by the rxtx NAPI poll to ensure XDP Tx ZC
operation is continuously polling for next Tx frame. This gives
benefit of lower packet submission processing latency and jitter
under XDP Tx ZC mode.
Performance of tx-only using xdp-sock on Intel ADL-S platform is
the same with and without this patch.

The ISA DMA API is inconsistent between architectures, and while

cs89_dbg(1, debug, "%s: dma %lx %lx\n",
I tried a couple of approaches to handle this consistently across

Start supporting API version 66 for AX devices.
Th iwlwifi FW API is frozen every 6 weeks, so we need to bump the
newest version number that the driver supports accordingly. In this
specific case, support for new HW will only be possible with the new
FW version. This change still keeps backwards compatibility with
older FW API versions for existing devices.

The Samsung Galaxy Book Flex2 Alpha uses an ax201 with the ID a0f0/6074.
This works fine with the existing driver once it knows to claim it.
Simple patch to add the device.

Due to a rebase damage, we lost the rtnl_lock() when the patch was
sent out. This causes an RTNL imbalance and failed assertions, due to
missing RTNL protection, for instance:
RTNL: assertion failed at net/wireless/reg.c (4025)
WARNING: CPU: 60 PID: 1720 at net/wireless/reg.c:4025 regulatory_set_wiphy_regd_sync+0x7f/0x90 [cfg80211]
Call Trace:

iwl_opmode_register+0xd0/0x130 [iwlwifi]
init_module+0x23/0x1000 [iwlmvm]
Fix this by adding the missing rtnl_lock() back to the code.

Setting DSA_MAX_PORTS caused DSA to call b53 callbacks (e.g.
b53_disable_port() during dsa_register_switch()) for invalid
(non-existent) ports. That made b53 modify unrelated registers and is
one of reasons for a broken BCM5301x support.
This problem exists for years but DSA_MAX_PORTS usage has changed few
times. It seems the most accurate to reference commit dropping
dsa_switch_alloc() in the Fixes tag.

It isn't true that CPU port is always the last one. Switches BCM5301x
have 9 ports (port 6 being inactive) and they use port 5 as CPU by
default (depending on design some other may be CPU ports too).
A more reliable way of determining number of ports is to check for the
last set bit in the "enabled_ports" bitfield.
This fixes b53 internal state, it will allow providing accurate info to
the DSA and is required to fix BCM5301x support.
