Take advantage of the devlink instance lock for protecting
the port list. This will simplify locking even more once
all devlink callbacks hold the instance lock.
We need to add locking in nsim_dev_port_add_all() which used
to assume higher layer protection when accessing the list.

The PGID (Port Group ID) table holds port masks
for different purposes. The first 72 are reserved
for port destination masks, flood masks, and CPU
forwarding. The rest are shared between multicast,
link aggregation, and virtualization profiles. The
GLAG area is reserved to not be used by anything
else, since it is a subset of the MCAST area.
The arbiter keeps track of which entries are in
use. You can ask for a free ID or give back one
you are done using.

Due to the different definition of txbuf in NFDK comparing to NFD3,
there're no pre-allocated txbufs for xdp use in NFDK's implementation,
we just use the existed rxbuf and recycle it when xdp tx is completed.
For each packet to transmit in xdp path, we cannot use more than
`NFDK_TX_DESC_PER_SIMPLE_PKT` txbufs, one is to stash virtual address,
and another is for dma address, so currently the amount of transmitted
bytes is not accumulated. Also we borrow the last bit of virtual addr
to indicate a new transmitted packet due to address's alignment
attribution.

Add new data path. The TX is completely different, each packet
has multiple descriptor entries (between 2 and 32). TX ring is
divided into blocks 32 descriptor, and descritors of one packet
can't cross block bounds. The RX side is the same for now.
ABI version 5 or later is required. There is no support for
VLAN insertion on TX. XDP_TX action and AF_XDP zero-copy is not
implemented in NFDK path.
Changes to Jakub's work:
* Move statistics of hw_csum_tx after jumbo packet's segmentation.
* Set L3_CSUM flag to enable recaculating of L3 header checksum
in ipv4 case.
* Mark the case of TSO a packet with metadata prepended as

Prepare for choosing data path based on the firmware version field.
Exploit one bit from the reserved byte in the firmware version field
as the data path type. We need the firmware version right after
vNIC is allocated, so it has to be read inside nfp_net_alloc(),
callers don't have to set it afterwards.

Currently after the hardware restart triggered from the driver,
the station interface connection remains intact, since a disconnect
trigger is not sent to userspace. This can lead to a problem in
targets where the wifi mac sequence is added by the firmware.
After the target restart, its wifi mac sequence number gets
reset to zero. Hence AP to which our device is connected will receive
frames with a wifi mac sequence number jump to the past, thereby
resulting in the AP dropping all these frames, until the frame
arrives with a wifi mac sequence number which AP was expecting.
To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.
The other targets are not affected by this change, since the hardware
params flag is not set.

1) XDP multi buffer support
This series enables XDP on non-linear legacy RQ in multi buffer mode.
When XDP is enabled, fragmentation scheme on non-linear legacy RQ is
adjusted to comply to limitations of XDP multi buffer (fragments of the
same size). DMA addresses of fragments are stored in struct page for the
completion handler to be able to unmap them. XDP_TX is supported.
XDP_REDIRECT is not yet supported, the XDP core blocks it for multi
buffer packets at the moment.

After introducing multi-buffer XDP_TX, the MLX5E_XDP_TX_DS_COUNT define
became misleading. It's no longer the DS count of an XDP_TX WQE, this
WQE can be longer because of fragments.
As this define is only used at one place in mlx5e_open_xdpsq(), it's
also not very useful anymore. This commit removes the define and puts
the calculation of ds_count for prefilled single-fragment WQEs inline.

When MPWQE is disabled, mlx5e_open_xdpsq() prefills the common fields of
WQEs in the XDP SQ to save time when sending packets.
mlx5e_xmit_xdp_frame() runs on the prefilled fields, however, sending
multi buffer XDP frames would require changing some of these fields on a
per-packet basis. Besides that, mlx5e_xmit_xdp_frame() will be used as a
fallback to send multi buffer XDP frames when MPWQE is enabled (MPWQE
can only handle linear packets).
In order to prepare for XDP multi buffer support, this commit introduces
a mode for mlx5e_xmit_xdp_frame() that fills all the fields itself.

When MPWQE is disabled, mlx5e_open_xdpsq prefills the common fields of
WQEs in the XDP SQ to save time when sending packets. One of such fields
is eseg->inline_hdr.sz, which can be either 0 or MLX5E_XDP_MIN_INLINE,
depending on the inline mode of the SQ.
The inline mode can't change during the lifetime of the SQ, so setting
this field again in mlx5e_xmit_xdp_frame is redundant. Moreover, the
xmit function only sets it to MLX5E_XDP_MIN_INLINE, but not to 0 in the
other case.

Use page_pool_set_dma_addr() to store the DMA address of a page inside
struct page, in order to avoid passing struct mlx5e_dma_info to XDP
handlers. Previously, struct mlx5e_dma_info was used to pass both the
DMA address and the page, and it worked well for the single-fragment
case.
When XDP multi buffer is in use, and a fragmented xdp_frame has to be
transmitted, the driver needs to know the DMA addresses of fragments,
however, the array of fragments in struct skb_shared_info doesn't
contain them. In order to pass the DMA addresses, the driver puts them
into struct page itself, which is accessible from the array of fragments
in struct skb_shared_info. The existing XDP handlers are modified to
remove the dependency on struct mlx5e_dma_info.

XDP multi buffer implementation in the kernel assumes that all fragments
have the same size. bpf_xdp_frags_increase_tail uses this assumption to
get the size of the last fragment, and __xdp_build_skb_from_frame uses
it to calculate truesize as nr_frags * xdpf->frame_sz.
The current implementation of mlx5e uses fragments of different size in
non-linear legacy RQ. Specifically, the last fragment can be larger than
the others. It's an optimization for packets smaller than MTU.
This commit adapts mlx5e to the kernel limitations and makes it use
fragments of the same size, in order to add support for XDP multi
buffer. The change is applied only if XDP is active, otherwise the old
optimization still applies.

This commit contains no functional change, except the SKB is built over

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.
platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.
It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

Host needs to set hardware data filter before entering WoW to
let firmware drop needless broadcast/mulitcast frames to avoid
frequent wakeup. Host clears hardware data filter when leaving WoW.

Implement net-detect feature by setting flag
WIPHY_WOWLAN_NET_DETECT if firmware supports this
feature. Driver sets the related PNO configuration
to firmware before entering WoW and firmware then
scans periodically and wakes up host if a specific
SSID is found.

Implement basic WoW functionalities such as magic-packet, disconnect
and pattern. The logic is very similar to ath10k.
When WoW is configured, ath11k_core_suspend and ath11k_core_resume
are skipped as WoW configuration and hif suspend/resume are done in
ath11k_wow_op_suspend() and ath11k_wow_op_resume().
