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.

The rep legacy RQ completion handling was missing the appropriate

When using libvirt to passthrough VF to VM it will always set the VF vlan
to 0 even if user didn’t request it, this will cause libvirt to fail to
boot in case the PF isn't eswitch owner.
Example of such case is the DPU host PF which isn't eswitch manager, so
any attempt to passthrough VF of it using libvirt will fail.
Fix it by not returning error in case set VF vlan is called with vid 0.

Add FEC counters' statistics of corrected_blocks and
uncorrectable_blocks, along with their lanes via ethtool.
HW supports corrected_blocks and uncorrectable_blocks counters both for
RS-FEC mode and FC-FEC mode. In FC mode these counters are accumulated
per lane, while in RS mode the correction method crosses lanes, thus
only total corrected_blocks and uncorrectable_blocks are reported in
this mode.

log_max_qp in driver's default profile #2 was set to 18, but FW actually
supports 17 at the most - a situation that led to the concerning print
when the driver is loaded:
"log_max_qp value in current profile is 18, changing to HCA capabaility
limit (17)"
The expected behavior from mlx5_profile #2 is to match the maximum FW
capability in regards to log_max_qp. Thus, log_max_qp in profile #2 is
initialized to a defined static value (0xff) - which basically means that
when loading this profile, log_max_qp value will be what the currently
installed FW supports at most.

In current switchdev implementation, every VF PR is assigned to
individual ring on switchdev ctrl VSI. For slow-path traffic, there
is a mapping VF->ring done in software based on src_vsi value (by
calling ice_eswitch_get_target_netdev function).
With this change, HW solution is introduced which is more
efficient. For each VF, src MAC (VF's MAC) filter will be created,
which forwards packets to the corresponding switchdev ctrl VSI queue
based on src MAC address.
This filter has to be removed and then replayed in case of
resetting one VF. Keep information about this rule in repr->mac_rule,
thanks to that we know which rule has to be removed and replayed
for a given VF.
In case of CORE/GLOBAL all rules are removed
automatically. We have to take care of readding them. This is done
by ice_replay_vsi_adv_rule.
When driver leaves switchdev mode, remove all advanced rules
from switchdev ctrl VSI. This is done by ice_rem_adv_rule_for_vsi.
Flag repr->rule_added is needed because in some cases reset
might be triggered before VF sends request to add MAC.

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 four RGMII interface modes take care of the required RGMII delay
configuration at the PHY and should not be limited by the network MAC
driver. Sadly, gemini was only permitting RGMII mode with no delays,
which would require the required delay to be inserted via PCB tracking
or by the MAC.
However, there are designs that require the PHY to add the delay, which
is impossible without Gemini permitting the other three PHY interface
modes. Fix the driver to allow these.

Locally generated packets ingress the device through its CPU port. When
the CPU port is congested and there are not enough credits in its
headroom buffer, packets can be dropped.
While this might be acceptable for data packets that traverse the
network, configuration packets exchanged between the host and the device
(EMADs) should not be subjected to this flow control.
The "sdq_lp" bit in the SDQ (Send Descriptor Queue) context allows the
host to instruct the device to treat packets sent on this queue as
"local processing" and always process them, regardless of the state of
the CPU port's headroom.
Add the definition of this bit and set it for the dedicated SDQ reserved
for the transmission of EMAD packets. This makes the "local processing"
bit in the WQE (Work Queue Element) redundant, so clear it.
