The patch seems to be against the 2.6.23 kernel, mdio_phy_addr was
removed in 2.6.24. The following compiles, although I haven't had
time to test it yet:


diff --git a/drivers/net/cris/eth_v10.c b/drivers/net/cris/eth_v10.c
index 65d0a91..c8bcb22 100644

 	}

 }
 


I'll add it to my queue (which will be published RSN :), thanks!
