[PATCH] Fix for the pcnet32 ethernet driver

[Manish Lachwani <mlachwani@prometheus.mvista.com>]

Hi Ralf,

This patch fixes the pcnet32 ethernet driver to clear any other interrupt
when setting interrupt enable in the pcnet32 interrupt handler. This has been
tested on the NEC CMB-VR4133 board.

Please review 

Thanks
