Message-Id: <1366390875-24570-6-git-send-email-rajesh.borundia@qlogic.com>

Subject: [PATCH net-next 5/8] qlcnic: Support VLAN id config.
o Add support for VLAN id configuration per VF using
iproute2 tool.
o VLAN id's 1-4094 are treated as PVID by the PF and
Guest VLAN tagging is not allowed by default.
o PVID is disabled when the VLAN id is set to 0
o Guest VLAN tagging is allowed when the VLAN id is set to 4095.
o Only one Guest VLAN id is supported.
o VLAN id can be changed only when the VF driver is not loaded.
