mac802154: Keep track of the channel when changed

2013-04-08T16:09:18+00:00

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.

mac802154: Use netif flow control

2013-04-07T21:06:43+00:00

Use netif_stop_queue() and netif_wake_queue() to control the flow of
packets to mac802154 devices.  Since many IEEE 802.15.4 devices have no
output buffer, and since the mac802154 xmit() function is designed to
block, netif_stop_queue() is called after each packet.

mac802154: Do not try to resend failed packets

2013-04-07T21:06:43+00:00

When ops->xmit() fails, drop the packet. Devices which support hardware
ack and retry (which include all devices currently supported by mainline),
will automatically retry sending the packet (in the hardware) up to 3
times, per the 802.15.4 spec.  There is no need, and it is incorrect to
try to do it in mac802154.

mac802154: use kfree_skb() instead of dev_kfree_skb()

2012-11-30T17:19:24+00:00

kfree_skb() indicates failure, which is where this is being used.

mac802154: fix memory leaks

2012-11-30T17:19:24+00:00

kfree_skb() was not getting called in the case of some failures.
This was pointed out by Eric Dumazet.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2012-06-29T00:37:00+00:00

Conflicts:
	drivers/net/caif/caif_hsi.c
	drivers/net/usb/qmi_wwan.c

The qmi_wwan merge was trivial.

The caif_hsi.c, on the other hand, was not.  It's a conflict between
1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform
device with ops structure.") in the net-next tree and commit
39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.

I did my best with that one and will ask Sjur to check it out.
