Only distinct use is checking if NETIF_F_NOCACHE_COPY should be
enabled by default. The check heuristics is altered a bit here,
so it hits other people than before. The default shouldn't be
trusted for performance-critical cases anyway.
For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.

The IEEE 802.15.4 drivers were compiled by default with debugging,
which caused them to be rather chatty and slow. This patch silences
them. People debugging drivers can still add a #define DEBUG in the
beginning of the respective file or use dynamic debug
This patch also removes the now unused option CONFIG_FFD.

Previously dev.platform_data was used to store a pointer to net device.
Now this code was gone. Drop it.

Force dev_alloc_name() to be called from register_netdevice() by
dev_get_valid_name(). That allows to remove multiple explicit
dev_alloc_name() calls.
The possibility to call dev_alloc_name in advance remains.
This also fixes veth creation regresion caused by

Follow the usual pattern of devices registration by adding new function
(wpan_phy_set_dev) that sets child->parent relationship and removing
parent argument from wpan_phy_register call.

IEEE 802.15.4-2006 defines channel pages that hold channels (max 32 pages,
27 channels per page). Allow the driver to specify supported channels
on pages, other than the first one.

This adds some perfunctory documentation comments to the IEEE 802.15.4
fakehard.c driver (Fake hard MAC) and the nl802154.h (outgoing netlink messages)
header.
These comments are not necessarily complete, but they do reference the
IEEE 802.15.4-2006 document where possible.

This patch is the result of an automatic spatch transformation to convert
all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.
Some occurences are missed by the automatic conversion, those will be
handled in a seperate patch.

menuconfig IEEE802154_DRIVERS is a bool that depends on tristate IEEE802154.
If the IEEE802154 symbol is 'm', the bool becomes 'y'.
This allows tristate symbols under IEEE802154_DRIVERS to be configured as
'y' and cause build problems.
Changing the menuconfig bool to a tristate fixes this.
