Subject: [PATCH v2 1/2] net/fec: replace hardcoded irq num with macro

From: Xiao Jiang <jgq516@...il.com>

Don't use hardcoded irq num and replace it with
FEC_IRQ_NUM macro.

The two patches are based on git://github.com/davem330/net-next.git
pls correct me if I still used wrong tree.

Thanks,
Xiao Jiang
