Subject: rx interrupt in userspace

Hi ,

 When flooding of network  packets happens on network card  ,  my
linux embedded box becomes unrepsonsive because softirq_rx eats up
hell a lot of CPU . I want  top half of tx interrupt to be in User
space . I want to implement some alogoritm in userspace  to drop
packets on high flooding and to keep other processes's some cycles .

Could you guide me a little on this , any online turorials or articles
or books , i can refer ?
Any similar implementation like this ?

Thanks,
Ratheesh.
