From 98f0334263f177dd22ca7c685cde04b47cc57b05 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 26 Nov 2014 12:42:02 +0100 Subject: cfg80211: clean up beacon loss CQM event Having it as a sub-event for RSSI thresholds is very ugly, but luckily no userspace actually uses the events yet. Move the event to its own function call internally and to its own event attribute in nl80211.

The maximum number of General Bytes is calculated by the maximum number of data bytes in the ATR_REQ/ATR_RES, substracted by the number of mandatory data bytes.
