[dpdk-dev] [PATCH] net/iavf: fix port VLAN cfg err for AVF with SVM

[dpdk-dev] [PATCH] net/iavf: fix port VLAN cfg err for AVF with SVM

[Junfeng Guo]

For AVF with single vlan mode (SVM), port vlan stripping config
has already been disabled by PF. In this scenario, the error of
-ENOTSUP can be ignored.

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