Fix the rx code path that does not handle the full rx ring correctly.

When the rx ring is set to the max. size (i.e. 255), the consumer and
producer indices will be the same when completing an rx packet. Fix
the rx code to handle this condition properly.

Support WoL during shutdown by calling
tg3_set_power_state(tp, PCI_D3hot) during tg3_close().

Change the power state parameter to pci_power_t type and use
constants defined in pci.h.

Certain ethtool operations cannot be performed after tg3_close()
because the device will go to low power state. Add return -EAGAIN
in such cases where appropriate.

This patch reduces the size of 'struct ip_conntrack' on systems with NAT

we only support one sequence number modification per window anyway, and
one such modification is not going to exceed 32kB ;)

this patch adds support to the VLAN driver to translate IF_OPER_DORMANT of the
underlying device to netif_dormant_on(). Beside clean state forwarding, this
allows running independant userspace supplicants on both the real device and
the stacked VLAN. It depends on my RFC2863 patch.

this patch adds a dormant flag to network devices, RFC2863 operstate derived
from these flags and possibility for userspace interaction. It allows drivers
to signal that a device is unusable for user traffic without disabling
queueing (and therefore the possibility for protocol establishment traffic to
flow) and a userspace supplicant (WPA, 802.1X) to mark a device unusable
without changes to the driver.

It is the result of our long discussion. However I must admit that it
represents what Jamal and I agreed on with compromises towards Krzysztof, but
Thomas and Krzysztof still disagree with some parts. Anyway I think it should
be applied.
