Hi,
Is it possible to use pf_ring aware drivers, e.g., ixgbe, on the reciever end
with Rx Checksum offload enabled?
We tried ethtool -K rx off with no aparent affect - the application is
recieving packets with incorrect checksum.
Possibly there is another way to either (1)drop malformed IP/TCP/.. packets (2)
recieved packets with both packet&calculated checksum(s) without consuming
software CPU?
The pf_ring is configured for non-DNA performance
# cat /proc/net/pf_ring/info
