From: Alexander Aring Date: Sun, 2 Nov 2014 05:44:54 +0000 (+0100) Subject: netdevice: add ieee802154_ptr to net_device X-Git-Tag: v3.19-rc1~32^2~17^2~6^2~216 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=98a18b6ffc79baa69f4a0d1bae58faf2a8aef4c8;p=platform%2Fkernel%2Flinux-exynos.git netdevice: add ieee802154_ptr to net_device This patch adds an ieee802154_ptr to the net_device structure. Furthermore the 802.15.4 subsystem will introduce a nl802154 framework which is similar like the nl80211 framework and a wpan_dev structure. The wpan_dev structure will hold additional net_device attributes like address options which are 802.15.4 specific. In the upcoming nl802154 implementation we will introduce a NL802154_FLAG_NEED_WPAN_DEV like NL80211_FLAG_NEED_WDEV. For this flag an ieee802154_ptr in net_device is needed. Additional we can access the wpan_dev attributes in upper layers like IEEE 802.15.4 6LoWPAN easily. Current solution is a complicated callback interface and getting these values over subif data structure in mac802154. Signed-off-by: Alexander Aring Acked-by: David S.
