we're using Micrel phy chip, in linux_src/.../drivers/net/phy, the micrel.c is there, thank God it's the correct chip version for me. Now i need to make a MAC driver for it. Where should i get started ? any samples ? Also why they just put the PHY code there, not the MAC ? How ppl can use it ? I hope MAC drivers are just using some generic PHY devices, then PHY is mapped to Micel in my case. Any help appreciated.
