Please help me to explain what exactly is happening here. Case 1: On x520, when I am giving the RX descriptor as 1024, it's not receiving any packets. There is no such huge traffic just arp and ping packets. But with 1024 as descriptor it is not accepting a single packet. But when I changed it to 1040, it starts working fine. Can anyone please explain what exactly happened? Total mbuf i allocated was 8192. Case 2: While in x710, if you use 1040 as rx descriptor, it won't let you configure. So I change it to 1024 but here also I am not getting any packet. Any suggestions? Thanks. BR, Nishant -- Rgds, Nishant
