Eric Dumazet ee3577c5d3 af_packet: do not call packet_read_pending() from tpacket_destruct_skb() ... [ Upstream commit 581073f626 ] trafgen performance considerably sank on hosts with many cores after the blamed commit. packet_read_pending() is very expensive, and calling it in af_packet fast path defeats Daniel intent in commit b013840810 ("packet: use percpu mmap tx frame pending refcount") tpacket_destruct_skb() makes room for one packet, we can immediately wakeup a producer, no need to completely drain the tx ring.
