[PATCH 3/5] ethtool: Call ethtool's get/set_settings callbacks with cleaned data

[David Decotigny <decot@google.com>]

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).

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

Tested: make allyesconfig compiles + e1000 & bnx2x work
