New Revision: 357327
URL: https://svnweb.freebsd.org/changeset/base/357327
Log:
Widen EPOCH(9) usage in mlx4en(4).
Make sure all receive completion callbacks are covered by the network
EPOCH(9), because this is required when calling if_input() and
ether_input() after r357012.
Convert some spaces to tabs while at it.
