Looks like there might be another incorrect bitmap usage for this in
ice_add_sw_recipe(). Care to fix it there as well?

Those are already fixed in one switchdev series and will be sent to IWL
soon.
I believe this patch would also make no sense after it's sent.

Hi Alexander,
When will the series be sent?
The bug causes a kernel panic. Will the series target net.git?

The global fix is here: [0]
It's targeting net-next.

I don't know what the best way here would be. Target net instead or pick
your fix to net and then fix it properly in net-next?

Michal

Thanks,
