bnxt_en: Query default VLAN before VNIC setup on a VF

Browse Source 
[ Upstream commit 1a9e4f501b ]

We need to call bnxt_hwrm_func_qcfg() on a VF to query the default
VLAN that may be setup by the PF.  If a default VLAN is enabled,
the VF cannot support VLAN acceleration on the receive side and
the VNIC must be setup to strip out the default VLAN tag.  If a
default VLAN is not enabled, the VF can support VLAN acceleration
on the receive side.  The VNIC should be set up to strip or not
strip the VLAN based on the RX VLAN acceleration setting.

Without this call to determine the default VLAN before calling
bnxt_setup_vnic(), the VNIC may not be set up correctly.  For
example, bnxt_setup_vnic() may set up to strip the VLAN tag based
on stale default VLAN information.  If RX VLAN acceleration is
not enabled, the VLAN tag will be incorrectly stripped and the
RX data path will not work correctly.

Fixes: cf6645f8eb ("bnxt_en: Add function for VF driver to query default VLAN.")
