patch 'net/iavf: remove error logs for VLAN offloading' has been queued to stable release 21.11.7

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/13/24. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/22e7e531ce15b67a31fb150882d9689b6b029afc

Thanks.

Kevin

Subject: [PATCH] net/iavf: remove error logs for VLAN offloading

[ upstream commit 325764b3a20a16a7a997a324cc0b93367eb7f3e1 ]

This was reported by RH QE.

When a vlan is enforced on a VF via an administrative configuration on
the PF side, the net/iavf driver logs two error messages.
Those error messages have no consequence on the rest of the port
initialisation and packet processing works fine.

[root@toto ~] # ip l set enp94s0 vf 0 vlan 2
[root@toto ~] # dpdk-testpmd -a 0000:5e:02.0 -- -i
...
Configuring Port 0 (socket 0)
iavf_dev_init_vlan(): Failed to update vlan offload
iavf_dev_configure(): configure VLAN failed: -95
iavf_set_rx_function(): request RXDID[1] in Queue[0] is legacy, set
	rx_pkt_burst as legacy for all queues

The first change is to remove the error log in iavf_dev_init_vlan().
This log is unneeded since all error path are covered by dedicated log
messages already.

Then, in iavf_dev_init_vlan(), requesting all possible VLAN offloading
must not trigger an ERROR level log message. This is simply confusing,
as the application may not have requested such vlan offloading.
The reason why the driver requests all offloading is unclear so keep it
as is. Instead, rephrase the log message and lower its level to INFO.

Fixes: 1c301e8c3cff ("net/iavf: support new VLAN capabilities")
