This patch adds a wpan_dev_list list into cfg802154_registered_device struct. Also adding new wpan_dev into this list while cfg802154_netdev_notifier_call.

Currently we ensure that the skb is freed on every error path in IPHC decompression which makes it easy to introduce skb leaks. By centralising the skb_free into the receive function it makes future decompression routines easier to maintain. It does come at the expense of ensuring that the skb passed into the decompression routine must not be copied.

This patch removes the get_phy callback from mlme ops structure. Instead we doing a dereference via ieee802154_ptr dev pointer.

The 6lowpan ipv6 header compression was causing problems for other interfaces that expected a ipv6 header to still be in place, as we were replacing the ipv6 header with a compressed version. This happened if you sent a packet to a multicast address as the packet would be output on 802.15.4, ethernet, and also be sent to the loopback interface. The skb data was shared between these interfaces so all interfaces ended up with a compressed ipv6 header. The solution is to ensure that before we do any header compression we are not sharing the skb or skb data with any other interface. If we are then we must take a copy of the skb and skb data before modifying the ipv6 header. The only place we can copy the skb is inside the xmit function so we don't leave dangling references to skb. This patch moves all the header compression to inside the xmit function. Very little code has been changed it has mostly been moved from lowpan_header_create to lowpan_xmit. At the top of the xmit function we now check if the skb is shared and if so copy it. In lowpan_header_create all we do now is store the source and destination addresses for use later when we compress the header.
