Author: adrian Date: Tue Apr 10 06:25:11 2012 New Revision: 234085 URL: http://svn.freebsd.org/changeset/base/234085 Log: * Since the API changed along the -CURRENT path (december 2011), add a FreeBSD_version check. It should work fine for compiling on -HEAD, 9.x and 8.x. * Conditionally compile the 11n options only when 11n is enabled. The above changes allow the ath(4) driver to compile and run on 8.1-RELEASE (Hi old PC-BSD!) but with the 11n stuff disabled. I've done a test against the net80211 and tools in 8.1-RELEASE. The NIC used in testing is the AR2427 in an EEEPC. Just to be clear - this change is to allow the -HEAD ath/hal/rate code to run on 9.x _and_ 8.x with no source changes. However, when running on earlier kernels, it should only be used for legacy mode. (Don't define ATH_ENABLE_11N.)
