From 1ce4784e675150748ff2d19b9a4ba287e3018905 Mon Sep 17 00:00:00 2001 From: Sukesh Srikakula Date: Fri, 13 May 2011 11:59:50 +0200 Subject: [PATCH] staging: brcm80211: Better debug support added to brcmfmac driver With the current implementation there is no way to selectively enable required debug messages, as all the messages are currently under WL_DBG. With this fix, we are introducing several log levels which will enable us to print only the required debug messages. WL_ERR --> Prints error messages WL_CONN --> Prints all debug messages pertaining to connection management WL_SCAN --> Prints all debug messages pertaining to scanning WL_TRACE --> Prints all trace(Enter/Exit) sequence of cfg80211 calls WL_INFO --> Prints all informational messages. By default, only WL_ERR messages are enabled.
