MFC r324792:
The remote DMA TCP portspace selector, RDMA_PS_TCP, is used for both
iWarp and RoCE in ibcore. The selection of RDMA_PS_TCP can not be used
to indicate iWarp protocol use. Backport the proper IB device
capabilities from Linux upstream to distinguish between iWarp and
RoCE. Only allocate the additional socket required for iWarp for RDMA
IDs when at least one iWarp device present. This resolves
interopability issues between iWarp and RoCE in ibcore

Use MAC-based GID format for the GID table entries in mlx5ib(4) to be
compatible with the ibcore module in FreeBSD 10-stable.

This fixes RDMA over VLAN, because the MAC-based GID format embeds
the VLAN ID into the GID itself and this is what ibcore expects when
requesting GID indexes from the GID cache.

RoCE V1.5 and V2 is not supported in 10-stable by mlx5ib(4).

MFC r322810 and r322830:
Add new mlx5ib(4) driver to the kernel source tree which supports
Remote DMA over Converged Ethernet, RoCE, for the ConnectX-4 series of
PCI express network cards.

There is currently no user-space support and this driver only supports
kernel side non-routable RoCE V1. The krping kernel module can be used
to test this driver. Full user-space support including RoCE V2 will be
added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise
this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel
module will only be built when WITH_OFED=YES is specified.
