Subject: pre-fetching skb for delayed send

Suppose one has a bridge-like thing that may store up packets
for a bit (100+ms) before sending them....

We notice that performance is very good if we can run with (near) zero
delay, but at higher delay, performance goes down significantly when attempting 10G
speeds.  I assume this is because we are sending skbs that are no longer in the cache...

So, is there an easy way to pre-fetch an skb and it's related pages?

Thanks,
Ben
