Thank you for explanation...
I'm sending 8 tcp streams with iperf3 from some box to openbsd ixl box
and here are results:
without diff
smc24# netstat -s | grep software-checksummed
5039250 input datagrams software-checksummed
2592718 output datagrams software-checksummed
2592709 packets software-checksummed
5039250 packets software-checksummed
0 input packets software-checksummed
0 output packets software-checksummed
cca 6.12 Gbits/sec
with diff
smc24# netstat -s | grep software-checksummed
0 input datagrams software-checksummed
2956546 output datagrams software-checksummed
2956537 packets software-checksummed
0 packets software-checksummed
0 input packets software-checksummed
0 output packets software-checksummed
cca 6.70 Gbits/sec
are result like those expected?
is forwarding testing any good for checksum offload diffs?
