[PATCH 01/16] wcn36xx: Add main.c

[Johannes Berg]

Just a cursory review ...

wouldn't that usually be written as

GRN_FLD |
SGI_20 |
...

(multiple similar places)

that n_patterns is pretty useless.

That's pointless

It seems to me this should not be here but you should have mac80211 set
something in e.g. bss_conf that indicates encryption?

You can't just "not support" them - you have to at least stop the
aggregation session, see the commit that introduced this.

You actually don't want to support WEP, not even in software? Otherwise
just leave this out and mac80211 will add it.

Your code with "wcn->current_vif = " etc. *really* doesn't look like you
support combinations. Are you positive this is OK?

Really? You don't even have hardware scan, so why?
