Changelog:
v4: Allow only IB_PORT_CM_SUP fake manipulation for RoCE providers.
v3: Improve [patch 1/4].
v2: Include fixes lines.
This series includes three patches which fix the return values from
modify_port() callbacks when they aren't supported.
Kamal Heib (4):
RDMA/core: Fix return code when modify_port isn't supported
RDMA/hns: Remove unsupported modify_port callback
RDMA/ocrdma: Remove unsupported modify_port callback
RDMA/qedr: Remove unsupported modify_port callback

Improving return code from ib_modify_port() by doing the following:
1- Use "-EOPNOTSUPP" instead "-ENOSYS" which is the proper return code.
2- Allow only IB_PORT_CM_SUP fake manipulation for RoCE providers that
didn't implement the modify_port callback, otherwise return "-EOPNOTSUPP".
Fixes: 61e0962d5221 ("IB: Avoid ib_modify_port() failure for RoCE devices")

There is no need to return always zero for function which is not
supported.
