   3 Subject: [PATCH] staging: octeon: sgmii to honor disabled dt node status
   4
   5 With this patch, sgmii interface device tree node could be disabled and
   6 that disabled interface will not be unnecessarily initialized.
   7
   8 It solves the problem with Octeon boards that have 8 sgmii or more ports
   9 initialized but have nothing connected to them.
