Revision 53240c208776d557dba9d7afedbcdbf512774c16 authored by Ali Saidi on 07 October 2008, 22:31:19 UTC, committed by David S. Miller on 07 October 2008, 22:31:19 UTC
From: Ali Saidi <saidi@engin.umich.edu> When TCP receive copy offload is enabled it's possible that tcp_rcv_established() will cause two acks to be sent for a single packet. In the case that a tcp_dma_early_copy() is successful, copied_early is set to true which causes tcp_cleanup_rbuf() to be called early which can send an ack. Further along in tcp_rcv_established(), __tcp_ack_snd_check() is called and will schedule a delayed ACK. If no packets are processed before the delayed ack timer expires the packet will be acked twice. Signed-off-by: David S. Miller <davem@davemloft.net>
