This external PHY could be a -switch connected through MII, which is often the case when this core is -used on home routers. The usage of an external PHY was assumed when the -PHY address 30 was used and an internal PHY was assumed when the PHY -address was different. To verify that b44_phy_reset() was called and -checked if it worked, otherwise PHY address 30 was assumed, an external -PHY. It is better to check the register which says which PHY is -connected to the MAC instead of checking the PHY address. -The interface to an external PHY was only activated when this register -was set. - -This also changes B44_FLAG_INTERNAL_PHY to B44_FLAG_EXTERNAL_PHY, it is -easier to check. - -Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> -Signed-off-by: David S.
