The description should mention that this also affects/fixes ixv(4), too.

I'll commit this for Jake and try to get it into 12-RELEASE

@krzysztof.galazka_intel.com I think @shurd's version here is better in that it masks isc_capabilities before togging RXCSUM/RXCSUM_IPV6. Though I think if you had added that, they might be roughly similar.

Looks like it does what it's supposed to.

iflib_admin_intr_deferred() called with STATE_LOCK() in a few places.

I've moved STATE_UNLOCK before iflib_admin_intr_defereed call although releasing lock just to immediately grab it again makes me a bit uneasy. Maybe it would be better idea to use mtx_owned in iflib_in_detach to check if this lock is already aquired?

Err, "arc patch" doesn't apply this cleanly to my svn tree -- it complains that it can't find the new files if_iavf.c, iavf_vc.c, and iavf.h to patch.

@erj do you want to ask RE permission to commit this?

My only nitpick is that ixlvc.c should probably be renamed to iavf_vc.c instead; it's supposed to contain the functions that communicate via the PF<->VF virtchannel.

Any last-minute assents or objections?

I'm going to try to get these committed, soon; I don't have any more planned changes.

@krzysztof.galazka_intel.com , you need to re-upload this patch

I can't tell if this is right or not, but it looks like an ok change to me.

Hrm, I don't think we can obtain CTX_LOCK() in those functions.

Wouldn't iflib_iov_intr_deferred() need it too?

It's a reasonable change, but it's still kind of a surprise to me that em doesn't support IPv6 hardware offloads.

You're apparently not allowed to delete changesets, so this'll have to be updated with the old diff.

rS339207 has the wrong Differential Revision, I think

Is there a reason not to do this in taskqgroup_detach()?

I don't see any obvious thing which prevents something being enqueued between the gtaskqueue_drain() and taskqgroup_detach() calls.

I'm confused; this is just doing a normal store / load for the in detach - you need a lock to serialize reading it with other operations.

Yes -- I did this quick update because someone mentioned the textproc/igor utility in another review. It also reminded me to come back to this.

• Run manpage through textproc/igor and fix resulting issues

I wish there was a previewer for these...

• ixl/ixlv Missing semicolon in DWB fix

The in-tree igb never sets IFLIB_ADMIN_ALWAYS_RUN. Is this for a modified version of igb?

I see IFM_40G_ER4 is missing from the table. There is only IFM_40G_LR4 currently.

Can you add IFM_40G_ER4 as part of this patch aswell?
