Subject: [PATCH net-next 3/8] bnxt_en: Use common function to get ethtool supported flags.

The supported bits and advertising bits in ethtool have the same
definitions.  The same is true for the firmware bits.  So use the
common function to handle the conversion for both supported and
advertising bits.
