[PATCH V3 for-next 3/9] IB/hns: Fix the value of device_cap_flags

From: Salil Mehta
Date: Thu Sep 15 2016 - 18:49:58 EST


From: Lijun Ou <oulijun@xxxxxxxxxx>

In the latest IB core version, it has some known issues
with memory registration using the local_dma_lkey.
Thus RoCE don't expose support for it, and remove
device->local_dma_lkey which is introduced to working systems.
