kirkwood and dove have a smaller FIFO than other "orion" SoCs. This
needs to be taken into account otherwise people using things like jumbo frames
will get into some troubles.

As a side note, this patch is an updated version of a patch sent some years
ago: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-June/017320.html
which seems to have been lost.
