Antonio Pastor 41d2e3be0f net: 802: LLC+SNAP OID:PID lookup on start of skb data ... [ Upstream commit 1e9b0e1c550c42c13c111d1a31e822057232abc4 ] 802.2+LLC+SNAP frames received by napi_complete_done() with GRO and DSA have skb->transport_header set two bytes short, or pointing 2 bytes before network_header & skb->data. This was an issue as snap_rcv() expected offset to point to SNAP header (OID:PID), causing packet to be dropped. A fix at llc_fixup_skb() (a024e377efed) resets transport_header for any LLC consumers that may care about it, and stops SNAP packets from being dropped, but doesn't fix the problem which is that LLC and SNAP should not use transport_header offset. Ths patch eliminates the use of transport_header offset for SNAP lookup of OID:PID so that SNAP does not rely on the offset at all. The offset is reset after pull for any SNAP packet consumers that may (but shouldn't) use it.
