From e3cf8b3f7b9eefbe1d39b160726d6e5c2cbb4c5d Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Mon, 29 Mar 2010 17:35:07 +0800 Subject: mac80211: support paged rx SKBs Mac80211 drivers can now pass paged SKBs to mac80211 via ieee80211_rx{_irqsafe}. The implementation currently use skb_linearize() in a few places i.e. management frame handling, software decryption, defragmentation and A-MSDU process. We will optimize them one by one later.

In order to meet these requirements, user space applications may need to clear authentication or association state in some cases. Currently, this can be done with deauth/disassoc command, but that ends up sending out Deauthentication or Disassociation frame unnecessarily. Add a new nl80211 attribute to allow this sending of the frame be skipped, but with all other deauth/disassoc operations being completed. Similar state change is also needed for IEEE 802.11r FT protocol in the FT-over-DS case which does not use Authentication frame exchange in a transition to another BSS. For this to work with cfg80211, an authentication entry needs to be created for the target BSS without sending out an Authentication frame. The nl80211 authentication command can be used for this purpose, too, with the new attribute to indicate that the command is only for changing local state. This enables wpa_supplicant to complete FT-over-DS transition successfully. Signed-off-by: Jouni Malinen Signed-off-by: John W.
