Many Ethernet MAC drivers want to limit the PHY to only advertise a
maximum speed of 100Mbs or 1Gbps. Rather than using a mask, make use
of the helper function phy_set_max_speed().

The driver indicates it can do 10/100 full and half duplex, plus 1G
Full. The datasheet indicates 1G half is also supported. So make use

It could be, this was added because there is a MAC which does not
support 1G half. Bit this is the wrong place to enforce this.

This is v3 of WOL/EEE functionality patch for atlantic driver.

In this patchset Yana Esina and Nikita Danilov implemented:

- Upload function to interact with FW memory
- Definitions and structures necessary for the correct operation of Wake ON Lan
- The functionality Wake On Lan via ethtool (Magic packet is supported)
- The functionality for Energy-Efficient Ethernet configuration via ethtool

Version 3:
- use ETH_ALEN instead of raw number

Version 2 has the following fixes:
- patchset reorganized to extract renaming and whitespace fixes into separate
  patches
- some of magic numbers replaced with defines
- reverse christmas tree applied

SKB list handling cleanups

This is a preparatory patch series which cleans up various forms of
sloppy SKB list handling, and makes certain semantics explicit.

We are trying to eliminate code that directly accesses the SKB
list and SKB queue head next/prev members in any way.  It is
impossible to convert SKB queue head over the struct list_head
while such code exists.

This patch series does not eliminate all such code, only the simplest
cases.  A latter series will tackle the complicated ones.

A helper is added to make the "skb->next == NULL means not on a list"
rule explicit, and another is added to combine this with list_del().
