From de5fad815703b5b24bc4726cd71422929537d259 Mon Sep 17 00:00:00 2001 From: Yoni Divinsky Date: Wed, 30 May 2012 11:36:39 +0300 Subject: mac80211: add op to configure default key id There are hardwares which support offload of data packets for example when auto ARP is enabled the hw will send the ARP response. In such cases if WEP encryption is configured the hw must know the default WEP key in order to encrypt the packets correctly. When hw_accel is enabled and encryption type is set to WEP, the driver should get the default key index from mac80211.

Remove the logic that tracks whether ARP filter is enabled or not and give the driver the total number of addresses instead of the length of the list so it can make its own decision.

Implement an IPv6 notifier in mac80211 to call the driver when addresses change. Unlike for IPv4, implement it as a callback rather than as a list in the BSS configuration, that is more flexible.
