In order for drivers to provide an alternate set of scan methods, these have to finally use an indirection table and all of the calls in ieee80211_scan.c need to use said table. For all existing drivers - this is basically a glorified, KBI-breaking functional no-op. This is also not the final form - too much functionality is currently hiding in ieee80211_scan_sw.c that should be in ieee80211_scan.c. That'll be the target of some follow-up commits. Note: * You have to recompile your kernel/drivers after this - the net80211 KBI has changed. * I'm not yet planning on bumping any versioning - I have a few more things to shuffle around. Tested: * urtwn(4) - STA mode * Intel 7260 in local repo - overriding the methods and table at attach time has the desired effect (ie, all the methods are called, but nothing is ever performed.)
