Description

It'd be useful to add support for the newer Intel X722 family of adapters that show up on Purley based systems.

To test this I first used an X722. I verified that the X722 which was copper properly connected and auto-negotiated to a 1 GbE switch and to a 10 GbE port. From there, I tested sending and receiving TCP and UDP traffic on and off VLANs. I verified that we were using checksums and that RSS was working and firing across multiple CPUs by doing something like:

# dtrace -n 'fbt::i40e_intr_msix:entry{ @[cpu] = count(); }' -n 'tick-1s{ printa(@); trunc(@); }'

In addition, I went through and checked that dlled and dltraninfo worked as I expected on both generations.

I then also went back and did a basic sanity check with the XXV710 (which uses the other controller). I did a basic perf tests and made sure that we were taking interrupts on multiple CPUs, as the RSS changes involved were somewhat more invasive to both controller families.
