bnxt_en: Validate vlan protocol ID on RX packets
[ Upstream commit 96bdd4b ] 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.
