Summary

Latest updates can be found here: https://github.com/intel-wired-ethernet/freebsd/tree/ixl-iflib

  • SR-IOV and the VF driver neither work nor compile
  • netmap is untested
  • VLANs do not work
  • no iWARP support
  • no nvmupdate support

Other bugs:

  • Memory leaks when passing traffic
  • Poor UDP throughput when using larger-than-mtu message sizes in netperf (e.g. -m > 1472 w/ 1500 mtu)
  • Occasional watchdog messages and/or MDD events
  • TX descriptor writeback mode causes interface watchdog/resets during UDP_STREAM netperf
Test Plan

Full regression, but details to be filled in later.

@erj please try along with latest iflib patch

Some files in ixl in the newest diff still won't apply cleanly.

  • fix interrupt assignment, LUT setup, and flowid assignment per Gallatin
  • don't ignore whitespace in case it's causing patch application problems for @erj

@erj I _just_ cloned https://github.com/freebsd/freebsd.git 10 minutes ago and the latest patch applies cleanly against it

Great.

My most recent changes may well have caused regressions so for the moment YMWV. Drew is at least testing the converted ixl in -STABLE.

Is this the final version? Or should there be a further update to this review?

Version string is here guys!

I can attempt to update the iflib version of ixl with what he have internally, but would it be a better idea to base it off what's in the iflib version of ixgbe right now (D5213)?

I'm working on this on a github branch here:

https://github.com/intel-wired-ethernet/freebsd/tree/iflib

It might be easier to follow along using that instead of updating this phabricator review. I think I'll return to this when it's more fully-baked.
