commit c4fb2cdf575d ("net: hns3: fix a bug for phy supported feature
initialization") adds default supported features for phy, but our hardware
also supports Asym Pause. This patch adds Asym Pause support to phy
default features to prevent Asym Pause can not be advertised when the phy
negotiates flow control.

When checking whether auto-negotiation is on, driver only needs to

Medford2 NICs support more than MC_CMD_MAC_NSTATS stats, and report the new
count in a field of MC_CMD_GET_CAPABILITIES_V4. This also means that the
end generation count moves (it is, as before, the last 64 bits of the DMA
buffer, but that is no longer MC_CMD_MAC_GENERATION_END).
So read num_mac_stats from the GET_CAPABILITIES response, if present;
otherwise assume MC_CMD_MAC_NSTATS; and always use num_mac_stats - 1 rather
than MC_CMD_MAC_GENERATION_END.

After TC offloads were converted to callbacks we have no choice
but keep track of the offloaded filter in the driver.
The check for nn->dp.bpf_offload_xdp was a stop gap solution
to make sure failed TC offload won't disable XDP, it's no longer
necessary. nfp_net_bpf_offload() will return -EBUSY on
TC vs XDP conflicts.

cls_bpf used to take care of tracking what offload state a filter
is in, i.e. it would track if offload request succeeded or not.
This information would then be used to issue correct requests to
the driver, e.g. requests for statistics only on offloaded filters,
removing only filters which were offloaded, using add instead of
replace if previous filter was not added etc.
This tracking of offload state no longer functions with the new
callback infrastructure. There could be multiple entities trying
to offload the same filter.
Throw out all the tracking and corresponding commands and simply
pass to the drivers both old and new bpf program. Drivers will
have to deal with offload state tracking by themselves.

- Open an IPv6 VXLAN interface (different socket)
- Remove one of the interfaces
With current implementation, the UDP port will be removed from our VXLAN
database and turn off the offloads for the other interface, which is
still active.
The reference count mechanism will only allow UDP port removals once all
consumers are gone.

Before the offending commit, mlx5 core did the IRQ affinity itself,
and it seems that the new generic code have some drawbacks and one
of them is the lack for user ability to modify irq affinity after
the initial affinity values got assigned.
The issue is still being discussed and a solution in the new generic code
is required, until then we need to revert this patch.
This fixes the following issue:
echo <new affinity> > /proc/irq/<x>/smp_affinity

This reverts commit a435393aca.

Compile Geneve match fields for offloading to the NFP. The addition of
Geneve overflows the 8 bit key_layer field, so apply extended metadata to
the match cmsg allowing up to 32 more key_layer fields.
Rather than adding new Geneve blocks, move the vxlan code to generic ipv4
udp tunnel structs and use these for both vxlan and Geneve.
Matches are only supported when specifically mentioning well known port
6081. Geneve tunnel options are not yet included in the match.
Only offload Geneve if the fw supports it - include check for this.
