This patch adds extended support for ibv_query_port.
This allows to request fields that aren't availible by the current
ibv_query_port API and avoid fetching from vendor library fields that
the user doesn't need, which gives more room for optimizations.

Add an enum that describes ibv_port_cap_flags that complies
with the respective kernel enum.
This value could be fetched when using ibv_query_port in
port_cap_flags.

libmlx4 is a library that allows programs to use RDMA "verbs" for
direct access to RDMA (currently InfiniBand and iWARP) hardware from
userspace.
The new stable release, 1.0.6, is available from
http://www.openfabrics.org/downloads/mlx4/libmlx4-1.0.6.tar.gz
with sha1sum

Joe, please get rid of the initial empty line you're adding to fw.c and
resubmit with Amir's ACK.
Thanks.
