Patch looks reasonable, if unconvnetionally presented ;) Thanks.
I fixed a bit of whitespace and converted mii_display_config() and
mii_relink() to take an unsigned long arguments as they're now a tasklet
callback.
Perhaps you could retest this sometime, please?

- fix for Bug 4310
- The fcc_enet.c, as distributed in 2.6.10, does not compile. Evidently
the 2.6 kernel no longer supports the schedule_task() and "struct
tq_struct" to go with it. Lines 73 through and including 96 of the
diffout file show the changes I made to port schedule_task() into
tasklet_schedule(). I should have reported this as a bug too but I
forgot about it.
- customize fcc_enet.c to work with my custom board. These changes are
conditional on CONFIG_EON8260 being defined.
