   4 Subject: [PATCH 03/14] net: dpaa2-eth: don't use -ENOTSUPP error code
   5
   6 dpaa2_eth_setup_dpni() is called from the probe path and
   7 dpaa2_eth_set_link_ksettings() is propagated to user space.
   8
   9 include/linux/errno.h says that ENOTSUPP is "Defined for the NFSv3
  10 protocol". Conventional wisdom has it to not use it in networking
  11 drivers. Replace it with -EOPNOTSUPP.
