bnxt_en: Validate vlan protocol ID on RX packets
[ Upstream commit 96bdd4b9ea7ef9a12db8fdd0ce90e37dffbd3703 ]
Only pass supported VLAN protocol IDs for stripped VLAN tags to the
stack. The stack will hit WARN() if the protocol ID is unsupported.
Existing firmware sets up the chip to strip 0x8100, 0x88a8, 0x9100.
Only the 1st two protocols are supported by the kernel.
