It's absolutely possible this has completely broken the ath driver. I'm going to spend the next few days throwing it against the hardware I have with me just to see if I broke anything during the merge. If you feel brave, throw on ATH_ENABLE_11N in your kernel config file and give it a go. If you're using legacy (non-11n) NICs, or you're not using 11N at home, please enable it too. It affects the non-11n TX path as well and I'd like to make absolutely sure this is still (mostly) working. Finally, if you -are- going to be testing this, I won't accept any error reports unless you've been running it with the -current debugging flags. That is, lock/witness debugging, asserts, and the memory allocator debugging. There's just too much that could be going wrong and I'd like to make sure that I have all of the relevant information from testers. Thanks again! Adrian
