btmtksdio belongs to WIFI/BT combo chip that would serve two radios in one
sdio_irq so that we have to move interrupt service to worker to ensure ISR
as short as possible.
The worker would serve the both Tx and Rx in a batch to effectively reduce
many interrupts to the host and to avoid excessive sdio lock contention
between various context (even from WiFi driver) and help to be more
efficient to complete command/event transation.

Add the missing bulk-out endpoint sanity check to probe() to avoid
division by zero in bfusb_send_frame() in case a malicious device has
broken descriptors (or when doing descriptor fuzz testing).
Note that USB core will reject URBs submitted for endpoints with zero
wMaxPacketSize but that drivers doing packet-size calculations still
need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip
endpoint descriptors with maxpacket=0")).

msft_opcode shall be use a vendor ogf (0x3f) but the check was
swifting the bits in the wrong order due to a missing parantesis
over val & 0xffff, but since the code already checks for values over
0xffff it shall not be necessary to perform that operation it now just
removes which makes it work properly when setting opcodes like 0xfce1.

mlx5-updates-2021-10-04
Misc updates for mlx5 driver
1) Add TX max rate support for MQPRIO channel mode
2) Trivial TC action and modify header refactoring
3) TC support for accept action in fdb offloads
4) Allow single IRQ for PCI functions
5) Bridge offload: Pop PVID VLAN header on egress miss
Vlad Buslov says:
=================
With current architecture of mlx5 bridge offload it is possible for a
packet to match in ingress table by source MAC (resulting VLAN header push
in case of port with configured PVID) and then miss in egress table when
destination MAC is not in FDB. Due to the lack of hardware learning in
NICs, this, in turn, results packet going to software data path with PVID
VLAN already added by hardware. This doesn't break software bridge since it
accepts either untagged packets or packets with any provisioned VLAN on
ports with PVID, but can break ingress TC, if affected part of Ethernet
header is matched by classifier.
Improve compatibility with software TC by restoring the packet header on
egress miss. Effectively, this change implements atomicity of mlx5 bridge
offload implementation - packet is either modified and redirected to
destination port or appears unmodified in software.

Check ethernet controller DT node for "mdio" subnode and use it with
of_mdiobus_register() when present. That allows specifying MDIO and its
PHY devices in a standard DT based way.
This is required for BCM53573 SoC support. That family is sometimes
called Northstar (by marketing?) but is quite different from it. It uses
different CPU(s) and many different hw blocks.
One of shared blocks in BCM53573 is Ethernet controller. Switch however
is not SRAB accessible (as it Northstar) but is MDIO attached.

1. Use info from DT if available
It allows describing for example a fixed link. It's more accurate than
just guessing there may be one (depending on a chipset).
2. Verify PHY ID before trying to connect PHY
PHY addr 0x1e (30) is special in Broadcom routers and means a switch
connected as MDIO devices instead of a real PHY. Don't try connecting to
it.

one required IRQ for control and at least one required IRQ for IO.

Actual tunnel interface can be created with a parameter "dev" [1],
which specifies the physical device to use for tunnel endpoint
communication. Pass this parameter to driver when looking up encap
route for offloads. So that a unicast route will be returned.

Also mlx5e_tc_sample_unoffload() should not return post_rule

Sample offload works with this NULL because many places of the

rule. Let's be persistent and avoid returning NULL anyway and return the
