-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 struct lowpan_priv_foobar *
-lowpan_foobar_priv(struct net_device *dev)
-{
-	return (struct 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.
