Subject: net/iavf: fix VLAN strip configuration
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=87b81daeeb871660cc1c96e64e1887c43ec4c3b2;p=dpdk.git

net/iavf: fix VLAN strip configuration

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")
