The changes are not new, just updated for the latest wireless-next. I did test 
it on wireless-next, apparently it has not synced with Linus' tree yet:

$ git describe wireless-next/master 
v3.14-rc2-938-g67b3bd4
$ git log --oneline -n4 rtlwifi-wireless-next 
cb39071 staging/rtl8821ae: remove unused allow_all_destaddr function
607693e staging/rtl8821ae: avoid accessing RCR directly
7db8deb rtlwifi: remove unused allow_all_destaddr functions
67b3bd4 brcmfmac: fallback to mimo_bw_cap for older firmwares

I must be missing something, since I subscribed to linux-wireless this month, 
I have not seen discussions about a replacement for rtl8821ae. Is this driver 
not published yet?

Ok, I kept those in separate patches, but will send different series next time 
if it is preferred.

Thanks,
Peter
