Proposal to increase Compressed Block Ack Timeout to fix A-MPDU transmission issues for 802.11 working at 2.4 GHz

The Block ACK timeouts is currently based on a minimal rate of 6 Mbit/s.

However, when operating at 2.4 GHz, it can be that block ACKs are being sent at lower rates (e.g. DSSS 1 Mbit/s).

I suggest to increase the Block Ack Timeout for 802.11n 2.4 Ghz (see attached patch).
