Merge branch 'fix-wrong-transport_header-when-sending-vlan-tagged-frames'
Wei Fang says:
====================
Fix wrong transport_header when sending VLAN-tagged frames
When sending a VLAN-tagged frame via AF_PACKET or tap, calling
skb_set_network_header() before skb_probe_transport_header() causes
the flow dissector to misinterpret the inner protocol header as a
VLAN header. As a result, transport_header is never set and remains
at its uninitialized sentinel value (~0U).
Move skb_probe_transport_header() to before skb_set_network_header()
so the flow dissector sees network_header still pointing to the VLAN
header and can correctly identify the transport layer.
