Ok...About EdcaTxop, what do you think about a unique class EdcaTxopN?
Another way could be to create a common abstract class which EdcaTxop
and EdcaTxopN inherits from.In the first implementation would be not
possible to use only 802.11e standard features without the 802.11n
features. There would be only possible (in an easy manner) to switch off
aggregation.Maybe the second implementation is better...with a common
interface we could use, in QstaWifiMac and in QapWifiMac, EdcaTxop or
EdcaTxopN.This also would help us to have in the same wlan many types of
 terminals (for example 802.11e and 802.11n terminals).

what do you think about?
