2016-12-22qedr: ignore inline flag in read verbsAmrani, Ram

2016-12-22qedr: modify QP state to error when destroying itAmrani, Ram
Current code didn't modify the QP state to error because it queried the QP state as a bitmap while it isn't. So the code never got executed. This patch fixes this and queries for each QP state respectively and not at once via a bitmask.

2016-12-13IB/core: Let create_ah return extended response to userMoni Shoua
Add struct ib_udata to the signature of create_ah callback that is implemented by IB device drivers. This allows HW drivers to return extra data to the userspace library. This patch prepares the ground for mlx5 driver to resolve destination mac address for a given GID and return it to userspace. This patch was previously submitted by Knut Omang as a part of the patch set to support Oracle's Infiniband HCA (SIF).
