ATM FreeBSD YukonII driver has stability issues and the driver needs big cleanups if we import the driver into src tree. But I wouldn't do the job and I'll spend my spare time to other thing. I know, from my previous experience(sk(4), stge(4)), how difficult to write a driver without a document and how hard to write a correct driver without knowing hardware internals. I'm sure there are many developers eager to write YukonII driver if they can access the hardware documentation. However I think there is no possibility that Marvell releases their chip documentations. > Has checksum offloading or the performance problems been fixed? Has > Marvell updated their driver?
