commit: 1b72c8ec227c007d6e49f7e780349d4db6ddb257 [25/29] sfp: move module eeprom ethtool access into netdev core ethtool
config: cris-allmodconfig (attached as .config)
compiler: cris-linux-gcc (GCC) 6.2.0
reproduce:
        wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 1b72c8ec227c007d6e49f7e780349d4db6ddb257
        # save the attached .config to linux build tree
        make.cross ARCH=cris
