svn commit: r322250 - head/sys/dev/mlx5/mlx5_en

[Hans Petter Selasky]

Author: hselasky
Date: Tue Aug  8 11:36:57 2017
New Revision: 322250
URL: https://svnweb.freebsd.org/changeset/base/322250

Log:
  Count drop events due to lack of PCI bandwidth as queue drops and not as
  input errors in the mlx5en(4) driver. This improves the sysadmin view of
  physical port errors.
