Subject: [PATCH] mac80211: do not convert to A-MSDU if frag/subframe
|
|
limited
|
|
|
|
Do not start to aggregate packets in a A-MSDU frame (converting the
|
|
first subframe to A-MSDU, adding the header) if max_tx_fragments or
|
|
max_amsdu_subframes limits are already exceeded by it. In particular,
|
|
this happens when drivers set the limit to 1 to avoid A-MSDUs at all.
