mac802154: don't warn on unsupported frames

2016-09-19T18:19:34+00:00

Just because we don't support certain types of frames yet doesn't mean
we have to flood the message log with warnings about "invalid" frames.

mac802154: Delete an unnecessary check before the function call "kfree_skb"

2015-11-19T16:50:32+00:00

The kfree_skb() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

mac802154: add comments for llsec issues

2015-09-30T11:16:44+00:00

While doing a little test with the llsec implementation I saw these
issues. We should move decryption and encruption somewhere else,
otherwise while capturing with wireshark the mac header shows secuirty
fields but the payload is plaintext.

A complete other issue is what doing with HardMAC drivers where the
payload is always plaintext. I think we need a special handling then in
userspace. We currently doesn't support any HardMAC transceivers, so we
should fix the first issue for SoftMAC transceivers.

mac802154: fix ieee802154_rx handling

2015-07-23T15:10:50+00:00

Instead of passing ieee802154_hw pointer to ieee802154_rx,
we can directly pass the ieee802154_local pointer.

mac802154: do not export ieee802154_rx()

2015-07-23T15:10:50+00:00

Right now there are no other users for ieee802154_rx()
in kernel. So lets remove EXPORT_SYMBOL() for this.

Also it moves the function prototype from global header
file to local header file.

mac802154: cfg: add suspend and resume callbacks

2015-07-23T15:10:49+00:00

This patch introduces suspend and resume callbacks to mac802154. When
doing suspend we calling the stop driver callback which should stop the
receiving of frames. A transceiver should go into low-power mode then.
Calling resume will call the start driver callback, which starts receiving
again and allow to transmit frames.

This was tested only with the fakelb driver and a qemu vm by doing the
following commands:

echo "devices" > /sys/power/pm_test
echo "freeze" > /sys/power/state

while doing some high traffic between two fakelb phys.

mac802154: remove unneeded vif struct

2015-06-07T07:13:32+00:00

This patch removes the virtual interface structure from sub if data
struct, because it isn't used anywhere. This structure could be useful
for give per interface information at softmac driver layer. Nevertheless
there exist no use case currently and it contains the interface type
information currently. This information is also stored inside wpan dev
which is now used to check on the wpan dev interface type.
