Interface for modules that implement contention-based channel access. For each frame, Contention listens on the channel for a DIFS (AIFS) period then for a random backoff period before transitting the frame, and defers when busy channel is sensed. After receiving a corrupted frame, EIFS is used instead of the original DIFS (AIFS).
