Subject: altera_tse: m88e1111s: Honor device flags regarding PHY interface mode
X-Git-Tag: v2011.12-rc1~428
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=15eb1069663676243a63a916fe482e751cd56deb;p=oweals%2Fu-boot.git

altera_tse: m88e1111s: Honor device flags regarding PHY interface mode

Note: This is kind of guess work. The current code is preserved for
all RGMII related modes. It is different for flags=0 (GMII) and flags=5
(SGMII). The last case, SGMII, is successfully tested on
Altera's Terasic DE4.
