iwlwifi: adding interrupt counter in debugfs for debugging
This patch adds interrupt statistics report to debugfs, this can help to understand number of interrupts happened which including HW/SW error for easier and better debugging. in /sys/kernel/debug/ieee80211/phyN/iwlagn/data directory use "cat interrupt" to view the current interrupt counter use "echo 0 > interrupt" to clear interrupt counter Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
