Subject: netif_receive_skb is taking long time

Hi,

In my NIC driver "netif_receive_skb" is taking too long time. Almost 3375 neno seconds. Which is more than whole packet processing from interrupt.

Could anyone please help me to understand what could be the reason behind this? How to solve it to take minimum time?

Is there any standard calls which we need to follow in order to get faster performance?

Regards,
Keyur
