   4 Subject: [PATCH 19/30] net: dsa: mt7530: remove .mac_port_config for MT7988
   5  and make it optional
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 For the switch on the MT7988 SoC, the mac_port_config member for ID_MT7988
  11 in mt753x_table is not needed as the interfaces of all MACs are already
  12 handled on mt7988_mac_port_get_caps().
  13
  14 Therefore, remove the mac_port_config member from ID_MT7988 in
  15 mt753x_table. Before calling priv->info->mac_port_config(), if there's no
  16 mac_port_config member in mt753x_table, exit mt753x_mac_config()
  17 successfully.
  18
  19 Remove calling priv->info->mac_port_config() from the sanity check as the
  20 sanity check requires a pointer to a mac_port_config function to be
  21 non-NULL. This will fail for MT7988 as mac_port_config won't be a member of
  22 its info table.
