Backporting mac80211 plugin. Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb): git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git This plugin adds changed field resolving for mac80211:drv_bss_info_changed tracepoint event. The diff of 'perf script' output generated by old and new code: (data was generated by 'perf record -e 'mac80211:drv_bss_info_changed' -a') --- script.mac80211.old +++ script.mac80211.new - ifconfig 3711 [000] 1290.446492: mac80211:drv_bss_info_changed: phy0 vif:wlan0(2) changed:0x309f + ifconfig 3711 [000] 1290.446492: mac80211:drv_bss_info_changed: phy0 vif:wlan0(2) + assoc:0 aid:2 cts:0 shortpre:0 shortslot:0 dtimper:1 + bcnint:102 assoc_cap:0x431 basic_rates:0xf enable_beacon:0 + ht_operation_mode:0 Omitting the mac80211:drv_config tracepoint handling because the kernel tracepoint changed its prototype and the plugin handler is no longer working.
