net: remove useless prefetch() call There is no gain using prefetch() in dev_hard_start_xmit(), since we already had to read ops->ndo_select_queue pointer in dev_pick_tx(), and both pointers are probably located in the same cache line. This prefetch call slows down fast path because of a stall in address computation. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
