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 a dedicated log
message 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.
