There's enough similar between phylib and the EMAC and sungem drivers that I'm considering a series of somewhat-mechanical patches to make EMAC and sungem use the "struct phy_device" and "struct mii_bus" from phylib, possibly abstracting out some helper functions along the way. >> Also, if I end up >> going that route, are there others available with other hardware >> variants who would be willing to test my patches on their boards? > > I have a large variety of boards that I can test with since the entire > 4xx line relies on this driver for on-board network. Wonderful! If/when I hack together a patch series I'll make sure to put you on the CC list. Thanks!
