Commit d3fd65484c781 ("net: core: add dev_sw_netstats_tx_add")
has added function "dev_sw_netstats_tx_add()" to update
net device per-cpu TX stats.
Use this function instead of ieee80211_tx_stats().

Heiner is actively working on this.
Heiner, would you mind looking at these three patches? If you have
these changes queued in your tree I'm happy to wait for them.

I think you can do the same with ieee80211_rx_stats().

This looks like a 1/3 but I only ever saw this, not the others.
Seems I should take this through my tree, any objections?

Hi,
> This looks like a 1/3 but I only ever saw this, not the others.
The rest are similar changes for openvswitch and xfrm subsystems, so
I've sent those to the list of maintainers I got from
scripts/get_maintainer.pl.

Go for it, you may need to pull net-next first but that should happen
soonish anyway, when I get to your pr.

Lev, please either post the patches separately (non-series) or make
them a proper series which has a cover letter etc. and CC folks on all
the patches.
Since there are no dependencies between the patches here you could have
gone for separate patches here.

Yeah, I'll fast forward once you have pulled that, and generally I don't
apply anything while I have open pull requests (in case I have to
rejigger or whatnot), so all should be well. :)
Thanks!

Resend would be great, please keep Heiner's review tags.

Understood, thanks.
