2017-01-24RDMA/qedr: Don't spam dmesg if QP is in error stateRam Amrani
It is normal to flush CQEs if the QP is in error state. Hence there's no use in printing a message per CQE to dmesg. Signed-off-by: Ram Amrani <Ram.Amrani@cavium.com> Signed-off-by: Michal Kalderon <Michal.Kalderon@cavium.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-12-22qedr: ignore inline flag in read verbsAmrani, Ram
In the current implementation a read verb with IB_SEND_INLINE may be illegally configured. In this fix we ignore the inline bit in the case of a read verb.

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).
