From 30686bf7f5b3c30831761e188a6e3cb33580fa48 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 2 Jun 2015 21:39:54 +0200 Subject: mac80211: convert HW flags to unsigned long bitmap As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.
