From ff0b007573c70be88c4efd3c1d8b41e9ba9710b3 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Tue, 11 Oct 2011 17:31:56 +0300 Subject: ath6kl: Add debugfs control for keepalive and disconnection timeout The new debugfs files keepalive and disconnect_timeout can be used to fetch the current values and to change the values for keepalive and disconnect event timeout (both in seconds).
