Currently much of the code assumes that a specific window has been
selected, while a few functions save and restore the window. This
makes it impossible to introduce fine-grained locking.
Make those assumptions explicit by introducing wrapper functions
to set the window and read/write a register. Use these everywhere
except vortex_interrupt(), vortex_start_xmit() and vortex_rx().
These set the window just once, or not at all in the case of
vortex_rx() as it should always be called from vortex_interrupt().
Cache the current window in struct vortex_private to avoid
unnecessary hardware writes.

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

The hash appears immediately before the packet data, not at the

The port profile information for a dynamic enic device is set by the upper
layers, that are oblivious to the device reset operation. We do not want a
reset operation erase the network state of a dynamic enic device as there
is no way to set up the port profile information again. Hence a lighter
reset operation called hang reset is used. Hang reset, unlike soft reset
does not reset the network state and resets the host side state only.
