Subject: [PATCH] mac80211: remove drop_unencrypted code
|
|
|
|
This mechanism was historic, and only ever used by IBSS, which
|
|
also doesn't need to have it as it properly manages station's
|
|
802.1X PAE state (or, with WEP, always has a key.)
|
|
|
|
Remove the mechanism to clean up the code.
|
|
