This (defaults to 10 frames) gives for a little headway in the TX ath_buf allocation, so buffer cloning is still possible. This requires a lot omre experimenting and tuning. It also doesn't stop a node/TID from consuming all of the available ath_buf's, especially when the node is going through high packet loss or only talking at a low TX rate. It also doesn't stop a paused TID from taking all of the ath_bufs. I'll look at fixing that up in subsequent commits. PR: kern/168170 |
