Detailed Description

Abstract interface for Rx processes.

The Rx process checks received frames for errors, manages the NAV, and notifies Tx processes about the channel state (free or busy). The channel is free only if it is free according to both the physical (CCA) and the virtual (NAV-based) carrier sense algorithms. Correctly received frames are sent up to UpperMac (see IUpperMac), corrupted frames are discarded. Tx processes are also notified about corrupted and correctly received frames. so they can switch between using DIFS/AIFS and EIFS according to the channel access procedure.
