This reverts commit 410bd754cd73c4a2ac3856d9a03d7b08f9c906bf.
The reverted commit had added a retry mechanism to the command entry
index allocation. The previous patch ensures that there is a free
command entry index once the command work handler holds the command

Tunnel device follows RFC 6040, and during decapsulation inner

Cells marked above are changed from original inner packet ip_ecn value.
Tc then matches on the modified inner ip_ecn, but hw offload which

Fix that by mapping all the cases of outer and inner ip_ecn matching,
and only supporting cases where we know inner wouldn't be changed by
decap, or in the outer ip_ecn=CE case, inner ip_ecn didn't matter.

Driver initiates DMA sync, hence it may skip CPU sync. Add
DMA_ATTR_SKIP_CPU_SYNC as input attribute both to dma_map_page and
dma_unmap_page to avoid redundant sync with the CPU.
When forcing the device to work with SWIOTLB, the extra sync might cause
data corruption. The driver unmaps the whole page while the hardware
used just a part of the bounce buffer. So syncing overrides the entire
page with bounce buffer that only partially contains real data.

As the possible failure of the allocation, the devm_ioremap() may return
NULL pointer.
Take tgec_initialization() as an example.
If allocation fails, the params->base_addr will be NULL pointer and will
be assigned to tgec->regs in tgec_config().
Then it will cause the dereference of NULL pointer in set_mac_address(),
which is called by tgec_init().
Therefore, it should be better to add the sanity check after the calling
of the devm_ioremap().

The role of ena_calc_max_io_queue_num() is to return the number
of queues supported by the device, which means the return value
should be >=0.
The function that calls ena_calc_max_io_queue_num(), checks
the return value. If it is 0, it means the device reported
it supports 0 IO queues. This case is considered an error
and is handled by the calling function accordingly.
However the current implementation of ena_calc_max_io_queue_num()
is wrong, since when it detects the device supports 0 IO queues,
it returns -EFAULT.
In such a case the calling function doesn't detect the error,
and therefore doesn't handle it.
This commit changes ena_calc_max_io_queue_num() to return 0
in case the device reported it supports 0 queues, allowing the
calling function to properly handle the error case.

ena_com_tx_comp_req_id_get() checks the req_id of a received completion,

the driver in an undefined state, where this completion is not properly
handled.
This commit adds a call to handle_invalid_req_id() in ena_clean_tx_irq()
and ena_clean_xdp_irq() which resets the device to fix the issue.
This commit also removes unnecessary request id checks from
validate_tx_req_id() and validate_xdp_req_id(). This check is unneeded

In case of an error in mlx5e_set_features(), 'netdev->features' must be
updated with the correct state of the device to indicate which features
were updated successfully.
To do that we maintain a copy of 'netdev->features' and update it after
successful feature changes, so we can assign it to back to
'netdev->features' if needed.
However, since not all netdev features are handled by the driver (e.g.
GRO/TSO/etc), some features may not be updated correctly in case of an
error updating another feature.
For example, while requesting to disable TSO (feature which is not
handled by the driver) and enable HW-GRO, if an error occurs during
HW-GRO enable, 'oper_features' will be assigned with 'netdev->features'
and HW-GRO turned off. TSO will remain enabled in such case, which is a
bug.
To solve that, instead of using 'netdev->features' as the baseline of
'oper_features' and changing it on set feature success, use 'features'
instead and update it in case of errors.

(cherry picked from commit 31108d142f3632970f6f3e0224bd1c6781c9f87d)
When there is ct or sample action, the ct or sample rule will be deleted
and return. But if there is an extra mirror action, the forward rule can't
be deleted because of the return.
Fix it by removing the return.

There are two ICOSQs per channel: one is needed for RX, and the other
for async operations (XSK TX, kTLS offload). Currently, the recovery
flow for both is the same, and async ICOSQ is mistakenly treated like
the regular ICOSQ.
This patch prevents running the regular ICOSQ recovery on async ICOSQ.
The purpose of async ICOSQ is to handle XSK wakeup requests and post
kTLS offload RX parameters, it has nothing to do with RQ and XSKRQ UMRs,
so the regular recovery sequence is not applicable here.

Both regular RQ and XSKRQ use the same ICOSQ for UMRs. When doing
recovery for the ICOSQ, don't forget to deactivate XSKRQ.
XSK can be opened and closed while channels are active, so a new mutex
prevents the ICOSQ recovery from running at the same time. The ICOSQ
recovery deactivates and reactivates XSKRQ, so any parallel change in
XSK state would break consistency. As the regular RQ is running, it's
not enough to just flush the recovery work, because it can be
rescheduled.

When TC classifier action offloads are disabled (CONFIG_MLX5_CLS_ACT in
Kconfig), the mlx5e_rep_tc_receive() function which is responsible for
passing the skb to the stack (or freeing it) is defined as a nop, and
results in leaking the skb memory. Replace the nop with a call to
napi_gro_receive() to resolve the leak.

SF do not directly control the PCI device. During recovery flow SF
should not be allowed to do pci disable or pci reset, its PF will do it.

In case IRQ layer failed to find or to request irq, the driver is
printing the first cpu of the provided affinity as part of the error
print. Empty affinity is a valid input for the IRQ layer, and it is
an error to call cpumask_first() on empty affinity.
Remove the first cpu print from the error message.
