From: Ben Hutchings <bhutchings@...arflare.com>
To: David Miller <davem@...emloft.net>
Cc: netdev@...r.kernel.org, linux-net-drivers@...arflare.com
Subject: [PATCH net-next-2.6 2/2] netdev: Use default implementation of
ethtool_ops::get_link where possible
Various drivers are using implementations of ethtool_ops::get_link
that are equivalent to the default ethtool_op_get_link(). Change
them to use that instead.
Signed-off-by: Ben Hutchings <bhutchings@...arflare.com>

I've tested the e1000e and sfc changes but not the others.
Ben.
