-- prepare private ieee80211 stack for merge with rtl8192su's version:
- - add hwsec_active flag to struct ieee80211_device
- - add bHwSec flag to cb_desc structure
-- switch to use shared "librtl" instead of private ieee80211 stack
-- switch to use LIB80211

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts. The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames. With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.
