Matt Carlson 34c92049ac tg3: Use new VLAN code
This patch pivots the tg3 driver to the new VLAN infrastructure.
All references to vlgrp have been removed.  The driver still attempts to
disable VLAN tag stripping if CONFIG_VLAN_8021Q or
CONFIG_VLAN_8021Q_MODULE is not defined.

Matt Carlson 41a8a7ee4a tg3: Fix read DMA FIFO overruns on recent devices
Earlier versions of tg3 devices had a problem where the read DMA FIFO
could be overrun in certain edge conditions.  The fix was to limit the
number of rx BDs the hardware would fetch at a time.  For later devices
(5761, 5784 and later ASIC revs), there is a hardware fix that must be
enabled to fix the same problem.  This patch adds that hardware fix.

There is a gap in the ASIC revision lineage where neither fix is
applied.  This is intentional as these ASIC revisions are not afflicted
by the bug.

length check.  It rounds out the implementation by relaxing the

Matt Carlson f89f38b8ec tg3: Unwedge stuck MSI-X vectors
The previous patch changed the code so that new rx buffer submissions to
the hardware stall if a new submission would overwrite data needed by an
unserviced rx packet.  On very busy 5717 and 57765 asic rev devices,
there is a corner case where the hardware will fail to assert an MSI-X
interrupt for rx traffic.  If that vector's interrupt never has another
reason to assert, any rx buffers held will never be serviced.  If the
buffers are never serviced and the hardware consumes all the available
rx packets for other rx rings, deadlock will result.
