Re: [Merge] ~jocave/netplan/+git/netplan:dont-rebind-mwifiex into netplan:master

 

I'm fine with applying this patch, but note that mac80211_hwsim is a bit special: it genuinely doesn't even advertise rebinding, but it's also just being used for testing so it doesn't matter much.

OTOH mwifiex_pcie actually controls real hardware, and with that "netplan apply" would stop working for renames. Obviously you do call netplan apply (otherwise you wouldn't run into the crash), so I figure you do want it to actually apply.

Can you please file a bug against the kernel with the logs and traces so that this gets fixed properly eventually?

I also have an inline comment, see below.

Please keep the original check for mac80211_hwsim only, as "does not support rebinding" is not actually true for mwifiex_pcie. For this one, rather log something like "crashes on rebind".
