Do not set rtnl_link_stats64 fields to zero, since they are zeroed

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the nlmon driver and leverage the network
core allocation.

To record the stats of header split packets, three stats are added in
the driver's ethtool stats.
- rx_hsplit_pkt is the split packets count with header split
- rx_hsplit_bytes is the received header bytes count with header split
- rx_hsplit_unsplit_pkt is the unsplit packet count due to header buffer
overflow or zero header length when header split is enabled
Currently, it's entering the stats_update critical section more than
once per packet. We have plans to avoid that in the future change to let
all the stats_update happen in one place at the end of
`gve_rx_poll_dqo`.

Add header buffers and ethtool support to enable header split via the
tcp-data-split flag in ethtool's ringparam config. A coherent dma memory
is allocated for the header buffers. There is one header buffer per ring
entry by calculating the offset to the header-buffers starting address.
The header buffer is always copied directly into the skb and payload is
always added as frags. When there is a header buffer overflow or the
header length is 0, the driver places the whole unsplit packet in frags.
When toggling header split, the driver will call gve_adjust_config to
set its queues appropriately. If header split is enabled by the user and
the max packet buffer size is no less than 4KB, driver will set the
packet buffer size as 4KB to support TCP_ZEROCOPY_RECEIVE. Otherwise the
driver will use the default 2KB as the packet buffer size.
`ethtool -G <dev> tcp-data-split on/off` is the command to toggle header
split.
`ethtool -g <dev>` will show the status of header split with the field
of `tcp-data-split`.

To enable header split via ethtool, we first need to query the device to
get the max rx buffer size and header buffer size. Add a device option
to get these values and store them in the driver. If the header buffer
size received from the device is non-zero, it means header split is
supported in the device.
Currently the max rx buffer size will only be used when header split is
enabled which will set the data_buffer_size_dqo to be the max rx buffer
size. Also change the data_buffer_size_dqo from int to u16 since we are
modifying it and making it to be consistent with max_rx_buffer_size.

If there is a lot of transmit traffic the driver can get into a
situation that the device is starved due to the doorbell never
being rung. This can happen if xmit_more is set constantly
and __netdev_tx_sent_queue() keeps returning false. Fix this
by checking if the queue needs to be stopped right before
calling __netdev_tx_sent_queue(). Use MAX_SKB_FRAGS + 1 as the
stop condition because that's the maximum number of frags
supported for non-TSO transmit.

Tx completion. However, this API is only meant to be called once

Currently the driver attempts to wake the Tx queue
for every descriptor processed. However, this is
overkill and can cause thrashing since Tx xmit can be
running concurrently on a different CPU than Tx clean.
Fix this by refactoring Tx cq servicing into its own
function so the Tx wake code can run after processing
all Tx descriptors.
The driver isn't using the expected memory barriers
to make sure the stop/start bits are coherent. Fix
this by making sure to use the correct memory barriers.
Also, the driver is using the wake API during Tx
xmit even though it's already scheduled. Fix this by
using the start API during Tx xmit.

Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

Forward skbs sent from one netdevsim port to its connected netdevsim
port using dev_forward_skb, in a spirit similar to veth.
Add a tx_dropped variable to struct netdevsim, tracking the number of
skbs that could not be forwarded using dev_forward_skb().
The xmit() function accessing the peer ptr is protected by an RCU read
critical section. The rcu_read_lock() is functionally redundant as since
v5.0 all softirqs are implicitly RCU read critical sections; but it is
useful for human readers.
If another CPU is concurrently in nsim_destroy(), then it will first set
the peer ptr to NULL. This does not affect any existing readers that
dereferenced a non-NULL peer. Then, in unregister_netdevice(), there is
a synchronize_rcu() before the netdev is actually unregistered and
freed. This ensures that any readers i.e. xmit() that got a non-NULL
peer will complete before the netdev is freed.
Any readers after the RCU_INIT_POINTER() but before synchronize_rcu()
will dereference NULL, making it safe.
The codepath to nsim_destroy() and nsim_create() takes both the newly
added nsim_dev_list_lock and rtnl_lock. This makes it safe with
concurrent calls to linking two netdevsims together.

The existing mv88e6390_g2_scratch_gpio_set_smi() cannot be used on the
88E6393X as it requires certain P0_MODE, it also checks the CPU mode
as it impacts the bit setting value.
This is all irrelevant for Amethyst (MV88E6191X/6193X/6393X) as only
the default value of the SMI_PHY Config bit is set to CPU_MGD bootstrap
pin value but it can be changed without restrictions so that GPIO pins
9 and 10 are used as SMI pins.
So, introduce Amethyst specific function and call that if the Amethyst
family wants to setup the external PHY.

The name mv88e6xxx_g2_scratch_gpio_set_smi is a bit ambiguous as it appears
to only be applicable to the 6390 family, so lets rename it to
mv88e6390_g2_scratch_gpio_set_smi to make it more obvious.

The i211 requires the same PTP timestamp adjustments as the i210,
according to its datasheet. To ensure consistent timestamping across
different platforms, this change extends the existing adjustments to
include the i211.
The adjustment result are tested and comparable for i210 and i211 based
systems.

The ppc4xx driver is not currently included in any defconfig and has
