On a PCIX bus, the 5701 has a bug which requires the driver to double
copy all rx packets.  The rx code uses the rx_offset device member as a
flag to determine if this workaround should take effect.  The following
patch will modify the rx_offset member such that this test will become
less clear.

The patch starts by integrating the workaround check into the packet
length check.  It rounds out the implementation by relaxing the
workaround restrictions if the platform has efficient unaligned
accesses.

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.

The most reliable and least intrusive way to work around the problem is
to detect the case where new submissions would overwrite existing data
and force all rx interrupt vectors to fire.

RSS ring 1 is responsible for submitting new rx buffers to the
hardware on behalf of all the other RSS rx return rings.  Up until now
this ring submitted its new rx buffers to the producer ring directly.
The following patch will require that this ring have a place to put
backlogged rx packets.  As a consequence, it can no longer submit new
buffers to the producer ring.

This patch adds code to allocate an extra shadow producer ring for this
RSS ring and adds RSS ring 1 to the list of rings needing buffer
transfers.
