Hi. I hope everyone is well and having a great day :) Just a quick question about the mcx (Mellanox 5th generation Ethernet device) drivers https://man.openbsd.org/mcx.4
The man page says nothing more than it supports; ConnectX-4 Lx EN ConnectX-4 EN ConnectX-5 EN ConnectX-6 EN I am looking for some clarity on what features and performance characteristics mcx boasts? For example are the following basic hardware features supported by this driver? IPv4 receive IP/TCP/UDP checksum offload IPv4 transmit TCP/UDP checksum offload VLAN tag insertion and stripping interrupt coalescing And what other features does it support? I also came across a comment in some forum a while back (so high quality information 😉) that mentioned Mellanox drivers in OpenBSD are SMP safe and so not giant-locked. Is this true? Thanks, Andy,
