X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=ad3620a072bc1ba93b0146f6f5467ae928b449a6;p=linux-2.6-omap-h63xx.git axnet_cs: fix phy_id detection for bogus Asix chip. axnet_cs: (1) Some Asix phy return bogus value except 0 or 0xffff. Skip this phy_id. (2) Some Asix chip need to set "select Internal PHY" bit at AX88190_init. Signed-off-by: Ken Kawasaki Signed-off-by: David S.
