svn commit: r272897 - head/sys/dev/e1000

[John Baldwin]

Author: jhb
Date: Fri Oct 10 16:36:25 2014
New Revision: 272897
URL: https://svnweb.freebsd.org/changeset/base/272897

Log:
  Various fixes to stats:
  - Read the counts of received, dropped, and transmitted management
    packets and add sysctl nodes for them.
  - Fix the total octets received/transmitted to read all 64 bits of
    the counters.
  - Add missing sysctl nodes for rlec, tncrs, fcruc, tor, and tot.
  - Remove spurious spaces.
