doc, net: Remove instruction to set net_device::trans_start
Commit 08baf561083bc27a953aa087dd8a664bb2b88e8e ('net: txq_trans_update() helper') made it unnecessary for most drivers to set net_device::trans_start (or netdev_queue::trans_start). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
