The commit e6278d92 ("mac802154: use header operations to
create/parse headers") included the header

		net/ieee802154_netdev.h

which had been included by the commit b70ab2e8 ("ieee802154:
enforce consistent endianness in the 802.15.4 stack"). Fix this
duplicate #include by deleting the latter one as the required header
has already been in place.

Use the operations on 802.15.4 header structs introduced in a previous
patch to create and parse all headers in the mac802154 stack. This patch
reduces code duplication between different parts of the mac802154 stack
that needed information from headers, and also fixes a few bugs that
seem to have gone unnoticed until now:

 * 802.15.4 dgram sockets would return a slightly incorrect value for
   the SIOCINQ ioctl
 * mac802154 would not drop frames with the "security enabled" bit set,
   even though it does not support security, in violation of the
   standard

Enable sparse warnings about endianness, replace the remaining fields
regarding network operations without explicit endianness annotations
with such that are annotated, and propagate this through the entire
stack.

Uses of ieee802154_addr_sa are not changed yet, this patch is only
concerned with all other fields (such as address filters, operation
parameters and the likes).

One of my pet coding style peeves is the practice of
adding extra return; at the end of function.
Kill several instances of this in network code.

I suppose some coccinelle wizardy could do this automatically.

Two sections checked whether the current channel != the new channel
without ever setting the current channel variables.

1. net/mac802154/tx.c: Prevent set_channel() from getting called every
time a packet is sent.

2. net/mac802154/mib.c: Lock (pib_lock) accesses to current_channel and
current_page and make sure they are updated when the channel has been
changed.

Bring-over mac802154_dev_get_dsn() function that was present in the
Linux ZigBee kernel. This function is called by the 6LoWPAN code in
order to properly set the DSN (Data Sequence Number) value in the IEEE
802.15.4 frame.
