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 <alex.aring@gmail.com> Cc: David S. Miller <davem@davemloft.net> --- Another option would be to combine ieee80211_ptr and ieee802154_ptr in an union. These pointer can't be used twice at the same time and the union solution will not make the struct net_device bigger. My working repository is bluetooth-next. Marcel will apply all 802.15.4 changes. That's why this patch should go into bluetooth-next. Then I can send new patches which depends on this patch for introducing wpan_dev and nl802154. include/linux/netdevice.h | 3 +++ 1 file changed, 3 insertions(+)
