[PATCH] arm driver net macb

[Paul Chavent <paul.chavent@fnac.net>]

[-- Attachment #1: Type: text/plain, Size: 292 bytes --]

When listing processes on a system with SOFT/HARD_IRQ enabled, the name of the ethernet device is [irq/eth%d] (instead of [irq/eth0] for example).

This patch call the request_irq function after having initialized the name of the device.
