====================
pull request: bluetooth-next 2015-08-16

Here's what's likely the last bluetooth-next pull request for 4.3:

 - 6lowpan/802.15.4 refactoring, cleanups & fixes
 - Document 6lowpan netdev usage in Documentation/networking/6lowpan.txt
 - Support for UART based QCA Bluetooth controllers
 - Power management support for Broeadcom Bluetooth controllers
 - Change LE connection initiation to always use passive scanning first
 - Support for new Silicon Wave USB ID

Please let me know if there are any issues pulling. Thanks.

Netdev private dataroom for 6lowpan interfaces:
All 6lowpan able net devices, means all interfaces with ARPHRD_6LOWPAN,
must have "struct lowpan_priv" placed at beginning of netdev_priv.
The priv_size of each interface should be calculate by:
dev->priv_size = LOWPAN_PRIV_SIZE(LL_6LOWPAN_PRIV_DATA);
Where LL_PRIV_6LOWPAN_DATA is sizeof linklayer 6lowpan private data struct.
To access the LL_PRIV_6LOWPAN_DATA structure you can cast:
lowpan_priv(dev)-priv;
to your LL_6LOWPAN_PRIV_DATA structure.
Before registering the lowpan netdev interface you must run:
lowpan_netdev_setup(dev, LOWPAN_LLTYPE_FOOBAR);
wheres LOWPAN_LLTYPE_FOOBAR is a define for your 6LoWPAN linklayer type of
enum lowpan_lltypes.
Example to evaluate the private usually you can do:
static inline sturct lowpan_priv_foobar *
lowpan_foobar_priv(struct net_device *dev)
{
return (sturct lowpan_priv_foobar *)lowpan_priv(dev)->priv;
}
switch (dev->type) {
case ARPHRD_6LOWPAN:
lowpan_priv = lowpan_priv(dev);
/* do great stuff which is ARPHRD_6LOWPAN related */
switch (lowpan_priv->lltype) {
case LOWPAN_LLTYPE_FOOBAR:
/* do 802.15.4 6LoWPAN handling here */
lowpan_foobar_priv(dev)->bar = foo;
break;
...
}
break;
...
}
In case of generic 6lowpan branch ("net/6lowpan") you can remove the check
on ARPHRD_6LOWPAN, because you can be sure that these function are called
by ARPHRD_6LOWPAN interfaces.
