[PATCH] libertas: remove structure WLAN_802_11_SSID and libertas_escape_essid
Replace WLAN_802_11_SSID with direct 'ssid' and 'ssid_len' members like ieee80211. In the process, remove private libertas_escape_essid and depend on the ieee80211 implementation of escape_essid instead. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
