2017-01-18 Thread Eugene M. Zheganin
Hi. Could someone recommend a decent 40Gbit adapter that are proven to be working under FreeBSD ? The intended purpose - iSCSI traffic, not much pps, but rates definitely above 10G. I've tried Supermicro-manufactured Intel XL710 ones (two boards, different servers - same sad story: packets loss, s

I can vouch for the Mellanox ConnectX-4 cards as working well, along with the Chelsio T5 stuff, both under heavy production usage in both routing and endpoint cases. In my testing the T5 was a slightly better option in situations demanding PPS with a higher ceiling and lower cpu utilization, b

Netmap TX with no impact to host

2017-01-18 Thread David Belle-Isle
Hi, I'm trying to open a netmap descriptor to an interface to send packets. However, I don't want to prevent the host to send and receive data (transparent). I don't think this should be hard but I can't figure out how to do this. I tried to run the bridge example in the FreeBSD distribution but
