Subject: [PATCH] netpoll: allow execution of multiple rx_hooks per interface

Hi,

this patch allows the registration and _execution_ of multiple netpoll
rx_hooks per interface. Currently, it is possible to register multiple
netpoll structures to one interface, _but_ only one single rx_hook (from
the netpoll struct that has been registered last) can be executed, which
was an oversight in the implementation [1].
So, this patch fixes it. I've sucessfully tested it within 2.6.32.2 with
the registration of multiple rx_hook clients for several times. I'd
appreciate comments / feedback.

Thanks,
Daniel
