    bnxt_en: Set backplane link modes correctly for ethtool
    
    [ Upstream commit 5007991670941c132fb3bc0484c009cf4bcea30f ]
    
    Use the return value from bnxt_get_media() to determine the port and
    link modes.  bnxt_get_media() returns the proper BNXT_MEDIA_KR when
    the PHY is backplane.  This will correct the ethtool settings for
    backplane devices.
