This could block the cleanup of an existing aggregation session, if a retransmission for a tid is issued, yet the tid is never scheduled again because of the cleanup state. Fix this by getting rid of as many subframes as possible, as early as possible, and immediately transmitting pending subframes as regular HT frames instead of waiting for the cleanup to complete. Drop all pending subframes while keeping track of the Block ACK window during aggregate tx completion to prevent sending out stale subframes, which could confuse the receiver side.
