Hi.
This patch lets gianfar work on 83xx (or 85xx??) boards that have
Generic PHYs on them that do _NOT_ happen to have an IRQ line wired to
external_15. Surely reasonable that if we can't ID the PHY that its
probably not irq-wired the Freescale-ADS "way"...
It was critical for us; perhaps usefull for others.
-dbu.
