mac802154: constify ieee802154_llsec_ops structure

2016-01-04T19:40:41+00:00

The ieee802154_llsec_ops structure is never modified, so declare it as
const.

Done with the help of Coccinelle.

mac802154: mac802154_mlme_start_req() optimisation.

2015-05-26T18:26:10+00:00

mac802154_mlme_start_req() calls
ieee802154_mlme_ops(dev)->llsec->set_params() on the net_device
passed into it, however, this net_device will always be a mac802154
net_device, so just call mac802154_set_params() directly instead.

mac802154: remove mib lock

2015-05-23T15:57:08+00:00

This patch removes the mib lock. The new locking mechanism is to protect
the mib values with the rtnl lock. Note that this isn't always necessary
if we have an interface up the most mib values are readonly (e.g.
address settings). With this behaviour we can remove locking in
hotpath like frame parsing completely. It depends on context if we need
to hold the rtnl lock or not, this makes the callbacks of
ieee802154_mlme_ops unnecessary because these callbacks hols always the
locks.

mac802154: use atomic ops for sequence incrementation

2015-05-23T15:57:08+00:00

This patch will use atomic operations for sequence number incrementation
while MAC header generation. Upper layers like af_802154 or 6LoWPAN
could call this function in a parallel context while generating 802.15.4
MAC header before queuing into wpan interfaces transmit queue.

cfg802154: introduce wpan phy flags

2015-05-19T09:44:42+00:00

This patch introduce a flag property for the wpan phy structure.
The current flag settings in ieee802154_hw are accessable in mac802154
layer only which is okay for flags which indicates MAC handling which
are done by phy. For real PHY layer settings like cca mode, transmit
power, cca energy detection level.

The difference between these flags are that the MAC handling flags are
only handled in mac802154/HardMac layer e.g. on an interface up. The phy
settings are direct netlink calls from nl802154 into the driver layer
and the nl802154 need to have a chance to check if the driver supports
this handling before sending to the next layer.

We also check now on PHY flags while dumping and setting pib attributes.
In comparing with MIB attributes the 802.15.4 gives us an default value
which we assume when a transceiver implement less functionality. In case
of MIB settings the nl802154 layer doesn't need to check on the
ieee802154_hw flags then.

ieee802154: rework cca setting

2014-12-18T23:19:23+00:00

The current cca setting handle is a driver specific call. We need to
introduce some 802.15.4 specific layer and mapping 802.15.4 cca modes to
driver specific ones inside the 802.15.4 driver. This patch will add
such 802.15.4 layer and mapping the cca settings to driver specific ones.

ieee802154: netlink add rtnl lock

2014-11-09T18:50:29+00:00

This patch adds rtnl lock hold mechanism while accessing wpan_dev
attributes. Furthermore these attributes should be protected by rtnl
lock and netif_running only.

mac802154: remove mac_params in sdata

This patch removes the mac_params from subif data struct. Instead we

ieee802154: remove mlme get_phy callback

2014-11-05T20:53:04+00:00

This patch removes the get_phy callback from mlme ops structure. Instead
we doing a dereference via ieee802154_ptr dev pointer. For backwards
compatibility we need to run get_device after dereference wpan_phy via
ieee802154_ptr.

ieee802154: remove nl802154 unused functions

2014-11-05T20:53:03+00:00

The include/net/nl802154.h file contains a lot of prototypes which are
not used inside of ieee802154 subsystem. This patch removes this file
and make the only one used prototype "ieee802154_nl_start_confirm" as
static declaration in ieee802154/nl-mac.c
