svn commit: r357327 - head/sys/dev/mlx4/mlx4_en

[Hans Petter Selasky]

Author: hselasky
Date: Fri Jan 31 10:41:47 2020
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.
