mac80211: use listen interval 5 as default
Currently if a driver does not set hw.max_listen_interval a listen interval of 1 is negotiated with the AP. Thus, the AP could drop buffered frames for us after just one beacon interval which can easily happen with the current powersave and scan implementation. To avoid this issue increase the default interval to 5 which should be a reasonable safe default. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.
