Although most of IB and iWARP are separated from each other,
there is some common code required to handle their shared
CM listen port. This code listens for CM events and then
dispatches the event to the appropriate transport, either
IB or iWARP.

Support for iWARP NICs is implemented as a separate
RDS transport from IB. The code, however, is very
similar to IB (it was forked, basically.) so let's keep
it in one changeset.

The reason for this duplicationis that despite its similarity
to IB, there are a number of places where it has different
semantics. iwarp zcopy support is still under development,
and giving it its own sandbox ensures that IB code isn't
disrupted while iwarp changes. Over time these transports
will re-converge.

Signed-off-by: NAndy Grover <andy.grover@oracle.com>
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

While arguably the fact that the underlying transport needs a
connection to convey RDS's datagrame reliably is not important
to rds proper, the transports implemented so far (IB and TCP)
have both been connection-oriented, and so the connection
state machine-related code is in the common rds code.

This patch also includes several work items, to handle connecting,
sending, receiving, and shutdown.

The remaining uses of tg3_nvram_read_swab() either intended to read the
data from NVRAM exactly as tg3_nvram_read_be32() did or hide deeper
interpretations of the data.  For the former case, a direct replacement
of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order.  For
the latter case, we remove tg3_nvram_read_swab() and document what the
code is really doing.
