There are three variants of the set_check_bssid functions:
- four that modify the beacon filter (through _rtl*_set_bcn_ctrl_reg)
- one (rtl8192se) that does not modify the beacon filter and writes
less bits (just RCR_BSSID instead of RCR_BSSID_{DATA,BCN})
- one (rtl8192cu) that modifies the beacon filter, and depending on
the chip version, sets the same bits as rtl8192se, or the other four.
I was not sure where to move the set_bcn_ctrl_reg functions, these
depend on a value from rtl*/reg.h. Perhaps the [gs]et_hw_reg functions
can be extended with these registers?
Thanks,
Peter
