Subject: [net-next v2 07/16] ixgbe: fix setting port VLAN

From: Emil Tantilov <emil.s.tantilov@...el.com>

This patch fixes couple of issues introduced by
commit 2b509c0cd292 ("ixgbe: cleanup ixgbe_ndo_set_vf_vlan")

- fix setting of the VLAN inside ixgbe_enable_port_vlan()
- disable the "hide VLAN" bit in PFQDE when port VLAN is disabled
