| Subject: ath9k: declare required extra tx headroom |
| |
| commit 029cd0370241641eb70235d205aa0b90c84dce44 upstream. |
| |
| ath9k inserts padding between the 802.11 header and the data area (to |
| align it). Since it didn't declare this extra required headroom, this |
| led to some nasty issues like randomly dropped packets in some setups. |
