[Hans Petter Selasky]

Author: hselasky
Date: Tue Aug 15 13:37:04 2017
New Revision: 322540
URL: https://svnweb.freebsd.org/changeset/base/322540

Log:
  MFC r322250:
  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.
