This patch adds dynamic LRO diable support for mlx4 net driver.
It also fixes a bug of mlx4, which checks NETIF_F_LRO flag in rx
path without rtnl lock.

(I don't have mlx4 card, so only did compiling test. Anyone who wants
to test this is more than welcome.)

This is based on Neil's initial work too, and heavily modified based
on Stanislaw's suggestions.

Applied to net-next-2.6

I'd really like the module options to just die as the dynamic
ethtool mechanism should be the only knob for this for consistency
with the rest of the drivers.
