Daniel Borkmann 8e2f1a63f2 packet: fix packet_direct_xmit for BQL enabled drivers ... Currently, in packet_direct_xmit() we test the assigned netdevice queue for netif_xmit_frozen_or_stopped() before doing an ndo_start_xmit(). This can have the side-effect that BQL enabled drivers which make use of netdev_tx_sent_queue() internally, set __QUEUE_STATE_STACK_XOFF from within the stack and would not fully fill the device's TX ring from packet sockets with PACKET_QDISC_BYPASS enabled. Instead, use a test without BQL bit so that bursts can be absorbed into the NICs TX ring. Fix and code suggested by Eric Dumazet, thanks!
