   4 Subject: [PATCH] WNM: Ignore WNM-Sleep Mode Request in wnm_sleep_mode=0 case
   5
   6 The hostapd wnm_sleep_mode parameter was previously used to control
   7 advertisement of WNM-Sleep Mode support, but it was not used when
   8 processing a request to use WNM-Sleep Mode. Add an explicit check during
   9 request processing as well so that any misbehaving station is ignored.
