Note: ***** The model lacks the HCCA, any management mechanisms like Association/Reassociation, Authentication / Deauthentication. In addition, no superframe structure with Beacon frames and no power-saving methods are supported (as in the original ns-2 model). The RTS/CTS mechanism, which is included in the legacy ns-802.11 model, has never been tested and verified. Therefore we do not recommend to use RTS/CTS without reviewing the code in detail. This model only works with ns-2.28. Several changes might be needed to use it in combination with other ns versions.

Please rerun make afterwards. - please set Mac/802_11e cfb_ to 1 (in tcl/lan/ns-mac.tcl) if you want to enable CFB in your simulations. Rerun make afterwards.
