noticed many differences in wlioctl.h of RC2 and of BRCM 4.0.0.7
Some that may need a closer look:
* WPA_AUTH and WPA_AUTH2 bitvectors (defined in BRCM, not in RC2)
* WL_SECPVT_DATA_LEN definition
* Radically changed datastructure in /* Event data type */ section of sta_info_t  (three new items in the structure)
* additional flags WL_STA_WDS and WL_STA_LINKUP
* changed definition of WLC_E_LAST and addition of WLC_E_TXFAIL
* missing WL_CHAN_xxx settings (6 pieces)
* missing WL_WDS_WPA_ROLE_xxx (3 pcs.)
* many things were deleted that are in RC2

Would these thing need being adapted if the latest wl driver binaries are used ?
