We need to respond to ipv6 namespace lookups when in suspend. This patch
adds the necessary changes to issue the appropriate firmware command on
suspend and resume to enter/exit firmware offloaded ns lookup.

The bot tested only ath-next from ath.git, not the master branch:

[auto build test ERROR on wireless-drivers-next/master]
[also build test ERROR on wireless-drivers/master ath6kl/ath-next v5.11-rc1 next-20201223]

I'm guessing that this build error is due to some API changes in
net-next. I'm planning to update ath.git tree today to v5.11, hopefully
that clears up the issue.

Hi,

Thanks for the help, we have switched to test on master branch.

The bot was correctly testing the ath-next branch, as I use that branch
to commit the patches. Can you still change the bot back to use
ath-next, just as it did previously?

Sorry for the confusion.

Got it, we'll still test ath-next branch.
