[Bug 1409904] Re: Needed patches for InfiniBand Support: Flow Steering and Offload Support + Fixes

[Rafael David Tinoco]

Packages libiverbs and libmlx4 do not break ABI compatibility thus
rdepends do not need to be recompiled.

"""
The abi_compat field of struct ibv_context is used to determine
support of verbs extensions.  As a result, support for ABI version < 2
is removed (corresponds to kernel releases 2.6.11-2.6.14 no longer
being supported).  The lowest ABI now supported is 3 (really 4 since
 2.6.15 was ABI 4, I don't see that ABI 3 was in a release).
"""

Included patch called "Infrastructure-to-support-verbs-extensions.patch"
only makes libibverbs not to support older kernels (ABI <= 2) which is
acceptable for Trusty's 3.13 kernels.

Attaching fixes for libibverbs and libmlx4 soon...
