Aside from the fact that the patch doesn't apply against the
current kernel due to the change of gianfar to use the phy
layer...why wouldn't you just set the board_flags field
appropriately in your board port? If you don't use a phy interrupt
then don't set the flag claiming that you do.  stx_gp3.c doesn't
make use of the phy interrupt functionality, as an example.

I looked at an older kernel and I'm not sure where you see external
15 being used. It seems to be EXT5 on all the Fscale boards.
