As I said before, I have a local tree with functioning, basic 11n HT/20 support. The driver needs further attention before we can enable HT modes and have the chipsets have even a remote hope of being stable and useful enough. There's also quite a bit missing from my "basic 11n HT/20 support" which doesn't even remotely work - eg legacy protection modes, making sure HT/40 channel protection works, broken A-MPDU support (which shouldn't be broken, that's another problem to fix) and rate control module stuff. It was just enough for me to verify that actual TX/RX of MCS rates worked (and it did, well enough.) If someone can help me source an AR9285 NIC then I can also work on that. Right now however, I'm just going to concentrate on the AR9160 and AR9220/AR9280 (same chipset, one being PCI and the other being PCIe.) As for turbo mode (and half/XR modes) and FF support - in ath9k, those are all "deprecated". If you have access to older chips (so AR5212/AR5213 and earlier) and would like to help debug this then please pipe up. Adrian
