Hello, I found this email in wireless.wiki.kernel and I hope it's the right one for asking questions about ath9k drivers. I've been having a problem for a few weeks already. I'm doing a project to modify ath9k_htc driver to be able to make virtual access points for individual devices. That's why, I'm looking for the part of the driver code, which handles sending ACK to connected devices according to BSSID addresses. I've already gone through a big part of the code, but I couldn't find this part. Don't you possibly know which part of the ath9k driver code handles ACK? Thank you very much for an answer.
