netdev: octeon_mgmt: Free TX skbufs in a timely manner.
We also reduce the high water mark to 1 so skbufs are not stranded for long periods of time. Since we are cleaning after each packet, no need to do it in the transmit path. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
