We use a kernel 2.6.14 on PPC platform (MPC 8555). The FCC driver

works

To submit a kernel patch upstream, the patch should be against the
latest kernel version which is 2.6.21-rc now.

well with a 100Mbps link. But it doesn't with a 10Mbps link. To
solve it, I modified the GFMR register init: removed TCI bit and

The fcc code in 8260_io has been obsoleted by fs_enet driver (drivers/net/fs_enet).
It is known to work with 85xx at least in recent kernels. If it does not for some reason,
please letus know.

Thanks,
