sfxge(4): rollback last seen VLAN TCI if Tx packet is dropped

Authored by arybchik on Nov 21 2018, 11:59 AM.



Early processing of a packet on transmit may change last seen
VLAN TCI in the queue context. If such a packet is eventually
dropped, last seen VLAN TCI must be set to its previous value.
