svn commit: r334880 - head/sys/dev/vnic

[Andrew Turner]

Author: andrew
Date: Sat Jun  9 14:47:49 2018
New Revision: 334880
URL: https://svnweb.freebsd.org/changeset/base/334880

Log:
  In the ThunderX BGX network driver we were skipping the NULL terminator
  when parsing the phy type, however this is included in the length returned
  by OF_getprop. To fix this stop ignoring the terminator.
