[dpdk-dev] [PATCH 1/3] net/i40e: remove virtual channel command for VLAN pvid

[Beilei Xing <beilei.xing@intel.com>]

Since there's no specific version number to distinguish
DPDK pf and Linux kernel pf, DPDK vf won't recognize if
host is DPDK pf or kernel pf. The specific virtual channel
commands for DPDK pf can be deleted.
This patch removes I40E_VIRTCHNL_OP_CFG_VLAN_PVID.
