This patch adds arbitrary SG list memory registration support which is pending on the device capability (Introduced in Mellanox ConnectX-4). Now that the core is able to handle sg lists, the addition of this support is pretty straight-forward and with minimal changes to the core and ULP conversion. Just add another MR creation type which is capable of handling SG lists with gaps (pending on the device capability). Patch 0001 - IB core flagging Patch 0002 - mlx5 support Patch 0003 - First consumer, iser initiator (more will follow!) This has come up just now because I've been waiting for FW cap exposure that now is included in patchset "Add memory window user-space support to mlx5" by Matan (so it obviously depends on it).
