For the section “11.9.16 IEEE 802.11 Statistics”, I have following suggestion:

How about we add some common Statistics information as per RFC1213-MIB? For 
example, ifInOctets, ifInUcastPkts. 

While for “11.9.16.  IEEE 802.11 Statistics”, it only defines some specific 
information for 802.11 implement, for example, RTS Failure Count.
