Ben Hutchings 9c4df53bc3 ethtool, mdio, mii: Specify MDIO information fields in struct ethtool_cmd
Add comments for ethtool_cmd::phy_address and
ethtool_cmd::mdio_support, and definitions of the flags currently
used in mdio_support.

In the mdio library, assert that its own flags continue to match those
in the ethtool interface.

In the mii library, use the ethtool flag definition and stop
including <linux/mdio.h>.

Matt Carlson 37f07023d3 net: Change mii to ethtool advertisement function names
This patch implements advice by Ben Hutchings to change the mii side of
the function names to look more like the register whose values they
convert.  New LPA translation functions have been added as well.

Matt Carlson 28011cf19b net: Add ethtool to mii advertisment conversion helpers
Translating between ethtool advertisement settings and MII
advertisements are common operations for ethernet drivers.  This patch
adds a set of helper functions that implements the conversion.  The
patch then modifies a couple of the drivers to use the new functions.

David Decotigny 7073949720 ethtool: cosmetic: Use ethtool ethtool_cmd_speed API
This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.

For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.

All drivers compiled with make allyesconfig ion x86_64 have been
updated.

Tested: make allyesconfig on x86_64 + e1000e/bnx2x work

David Decotigny 25db033881 ethtool: Use full 32 bit speed range in ethtool's set_settings
This makes sure the ethtool's set_settings() callback of network
drivers don't ignore the 16 most significant bits when ethtool calls
their set_settings().

All drivers compiled with make allyesconfig on x86_64 have been
updated.

David Decotigny 8ae6daca85 ethtool: Call ethtool's get/set_settings callbacks with cleaned data
This makes sure that when a driver calls the ethtool's
get/set_settings() callback of another driver, the data passed to it
is clean. This guarantees that speed_hi will be zeroed correctly if
the called callback doesn't explicitely set it: we are sure we don't
get a corrupted speed from the underlying driver. We also take care of
setting the cmd field appropriately (ETHTOOL_GSET/SSET).

This applies to dev_ethtool_get_settings(), which now makes sure it
sets up that ethtool command parameter correctly before passing it to
drivers. This also means that whoever calls dev_ethtool_get_settings()
does not have to clean the ethtool command parameter. This function
also becomes an exported symbol instead of an inline.

All drivers visible to make allyesconfig under x86_64 have been
updated.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
