svn commit: r285668 - stable/10/sys/dev/ixgbe

New Revision: 285668
URL: https://svnweb.freebsd.org/changeset/base/285668

Log:
  Loader tunable fetching has been broken on stable/10 since ix(4) rewrite
  introduced by r280182. FreeBSD-head doesn't need TUNABLE_INT() now with
  SYSCTL_INT() but stable/10 still does.
  Note: This is a direct commit to stable/10.
