For NGBE devices, the queue number is limited to be 1 when SRIOV is
enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is
used for queue, based on the previous patches. But for the hardware
design, the IRQ vector[1] must be allocated for use by the VF[6] when
the number of VFs is 7. So the IRQ vector[0] should be shared for PF
MISC and QUEUE interrupts.
+-----------+----------------------+
| Vector | Assigned To |
+-----------+----------------------+
| Vector 0 | PF MISC and QUEUE |
| Vector 1 | VF 6 |
| Vector 2 | VF 5 |
| Vector 3 | VF 4 |
| Vector 4 | VF 3 |
| Vector 5 | VF 2 |
| Vector 6 | VF 1 |
| Vector 7 | VF 0 |
+-----------+----------------------+
Minimize code modifications, only adjust the IRQ vector number for this
case.

Due to hardware limitations of NGBE, queue IRQs can only be requested
on vector 0 to 7. When the number of queues is set to the maximum 8,
the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by
MISC interrupt, and althrough the vector 8 is used by queue interrupt,
it is unable to receive packets. This will cause some packets to be
dropped when RSS is enabled and they are assigned to queue 8.
So revert the adjustment of the MISC IRQ location, to make it be the
last one in IRQ vectors.

The `tx_may_stop()` logic stops TX queues if free descriptors
(`sq->vq->num_free`) fall below the threshold of (`MAX_SKB_FRAGS` + 2).
If the total ring size (`ring_num`) is not strictly greater than this
value, queues can become persistently stopped or stop after minimal
use, severely degrading performance.
A single sk_buff transmission typically requires descriptors for:
- The virtio_net_hdr (1 descriptor)
- The sk_buff's linear data (head) (1 descriptor)
- Paged fragments (up to MAX_SKB_FRAGS descriptors)
This patch enforces that the TX ring size ('ring_num') must be strictly
greater than (MAX_SKB_FRAGS + 2). This ensures that the ring is
always large enough to hold at least one maximally-fragmented packet
plus at least one additional slot.

The virtqueue_resize() function was not correctly propagating error codes
from its internal resize helper functions, specifically
virtqueue_resize_packet() and virtqueue_resize_split(). If these helpers
returned an error, but the subsequent call to virtqueue_enable_after_reset()
succeeded, the original error from the resize operation would be masked.
Consequently, virtqueue_resize() could incorrectly report success to its
caller despite an underlying resize failure.
This change restores the original code behavior:
if (vdev->config->enable_vq_after_reset(_vq))
return -EBUSY;
return err;

When calling buf_to_xdp, the len argument is the frame data's length
without virtio header's length (vi->hdr_len). We check that len with
xsk_pool_get_rx_frame_size() + vi->hdr_len
to ensure the provided len does not larger than the allocated chunk
size. The additional vi->hdr_len is because in virtnet_add_recvbuf_xsk,
we use part of XDP_PACKET_HEADROOM for virtio header and ask the vhost
to start placing data from
hard_start + XDP_PACKET_HEADROOM - vi->hdr_len
not
hard_start + XDP_PACKET_HEADROOM
But the first buffer has virtio_header, so the maximum frame's length in
the first buffer can only be
xsk_pool_get_rx_frame_size()
not
xsk_pool_get_rx_frame_size() + vi->hdr_len
like in the current check.
This commit adds an additional argument to buf_to_xdp differentiate
between the first buffer and other ones to correctly calculate the maximum
frame's length.

When setting "ethtool -L eth0 combined 1", the number of RX/TX queue is
changed to be 1. RSS is disabled at this moment, and the indices of FDIR
have not be changed in wx_set_rss_queues(). So the combined count still

FDIR. Fix it for those devices that support FDIR.

I226 devices advertise support for the PCI-E link L1.2 substate. However,
due to a hardware limitation, the exit latency from this low-power state
is longer than the packet buffer can tolerate under high traffic
conditions. This can lead to packet loss and degraded performance.
To mitigate this, disable the L1.2 substate. The increased power draw
between L1.1 and L1.2 is insignificant.

Remove redundant netif_napi_del() call from disconnect path.
A WARN may be triggered in __netif_napi_del_locked() during USB device
disconnect:
WARNING: CPU: 0 PID: 11 at net/core/dev.c:7417 __netif_napi_del_locked+0x2b4/0x350
This happens because netif_napi_del() is called in the disconnect path while
NAPI is still enabled. However, it is not necessary to call netif_napi_del()
explicitly, since unregister_netdev() will handle NAPI teardown automatically
and safely. Removing the redundant call avoids triggering the warning.

The `dma_map_XXX()` functions can fail and must be checked using
`dma_mapping_error()`. This patch adds proper error handling for all
DMA mapping calls.
In `atl1_alloc_rx_buffers()`, if DMA mapping fails, the buffer is
deallocated and marked accordingly.
In `atl1_tx_map()`, previously mapped buffers are unmapped and the
packet is dropped on failure.
If `atl1_xmit_frame()` drops the packet, increment the tx_error counter.

It already depends on X86_32, but that's also set for ARCH=um.
Recent changes made UML no longer have IO port access since
it's not needed, but this driver uses it. Build it only for
HAS_IOPORT. This is pretty much the same as depending on X86,
but on the off-chance that HAS_IOPORT will ever be optional
on x86 HAS_IOPORT is the real prerequisite.

While we are indirectly draining our dedicated workqueue ggtt->wq
that we use to complete asynchronous removal of some GGTT nodes,
this happends as part of the managed-drm unwinding (ggtt_fini_early),
which could be later then manage-device unwinding, where we could
already unmap our MMIO/GMS mapping (mmio_fini).
This was recently observed during unsuccessful VF initialization:

During driver probe we might be briefly using CT safe mode, which
is based on a delayed work, but usually we are able to stop this
once we have IRQ fully operational. However, if we abort the probe
quite early then during unwind we might try to destroy the workqueue
while there is still a pending delayed work that attempts to restart
itself which triggers a WARN.
This was recently observed during unsuccessful VF initialization:
[ ] xe 0000:00:02.1: probe with driver xe failed with error -62
[ ] ------------[ cut here ]------------
[ ] workqueue: cannot queue safe_mode_worker_func [xe] on wq xe-g2h-wq

[ ] Call Trace:

[ ] call_timer_fn+0xa1/0x2a0
Exit the CT safe mode on unwind to avoid that warning.
