The 6205 (Taylor Peak) in the Lenovo X230 works fine in 5GHz 11a and 11n HT20, but not 11n HT40. The NIC goes RX deaf the moment HT40 is configured. It's so RX deaf that it doesn't even hear beacons and the firmware sends "BEACON MISS" events. That's pretty deaf. I tried configuring up the HT40 flags in monitor mode and it worked - so I assumed that doing the transition from 20 -> 40MHz channel configuration when going auth->assoc (ie, after the NIC has been partially configured) is a problem. So for now, let's just always set them if they're available. Tested: * Intel 5300, STA mode, 5GHz HT/40 AP; 2GHz HT/20 AP * Intel 6205, STA mode, 5GHz HT/40, HT20, 11a AP; 2GHz HT/20 AP This was pointed out to me by coworkers trying to use FreeBSD-HEAD in the office on their Thinkpad T420p laptops. TODO: * I don't like how the HT40 flags are configured - the whole interop/ protection config should be re-checked. Notably, I think curhtprotmode is 0 in a lot of cases, which means "no interoperability" and i think that's busted. Sponsored by: Norse Corp, Inc. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The `buildkernel` and `installkernel` targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information. Note: If you want to build and install the kernel with the `buildkernel` and `installkernel` targets, you might need to build world before. More information is available in the handbook. The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
