This corrects an regression introduced by "net: Use 16bits for *_headers
fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In
that case skb->tail will be a pointer whereas skb->transport_header
will be an offset from head. This is corrected by using wrappers that
ensure that comparisons and calculations are always made using pointers.

Similar to the problem in pktgen, netpoll uses skb_tail_offset()
too, as the code is copied from pktgen.

Also use return values of skb_put() directly, this will simiplify
the code.

skb_set_network_header() expects an offset based on the data pointer
whereas skb_tail_offset() also includes the headroom. This resulted
in the ip header being written in a wrong location.

Use return values of skb_put() directly and rely on skb->len to
set mac, network, and transport header.

The newly added sun4i-emac driver causes a build error when
CONFIG_NET_POLL_CONTROLLER is set, because it attempts to
assign a pointer to netdev->poll_controller, which has
been replaced with ops->ndo_poll_controller in 2.6.31!

The correct assignment is present as well, so we just need
to remove the wrong one.

mlx4 driver has a suboptimal memory allocation strategy for regular
MTU=1500 frames, as it uses two page fragments :

One of 512 bytes and one of 1024 bytes.

This makes GRO less effective, as each GSO packet contains 8 MSS instead
of 16 MSS.

Performance of a single TCP flow gains 25 % increase with the following
patch.

This patch improves the logic used by the mvneta driver to find a MAC
address for a particular interface. Until now, it was only looking at
the Device Tree, and if no address was found, was falling back to
generating a random MAC address.

This patch adds the intermediate solution of reading the MAC address
from the hardware registers, in case it has been set by the
bootloader. So the order is now:

 1) MAC address from the Device Tree
 2) MAC address from the hardware registers
 3) Random MAC address

This requires moving the MAC address initialization a little bit later
in the ->probe() code, because it now requires the hardware registers
to be remapped.

76723bca "net: mv643xx_eth: add DT parsing support" added a
dummy mv643xx_eth_shared_of_probe() fallback function with a
typo.

This adds the missing semicolon so we can build without CONFIG_OF
again, and changes both dummy functions to the more conventional
"static inline" syntax, which can avoid potential problems with
the empty macro.

this is a pull-request for net-next/master. It consists of two patches
by Fabio Estevam, cleaning up the flexcan driver (remove default
pinctrl and switch to SIMPLE_DEV_PM_OPS). A patch by me to simplify the
Kconfig [1] handling for flexcan. And a patch by Jingoo Han that
converts the can drivers to use platform_{get,set}_drvdata().

[1] My patch touches arch/{arm,powerpc}, so I collected Acked-bys from

Use the wrapper functions for getting and setting the driver data using
