Yixing Liu 487d65090a RDMA/hns: Fix the gid problem caused by free mr ... After the hns roce driver is loaded, if you modify the mac address of the network port, the following error will appear: __ib_cache_gid_add: unable to add gid fe80:0000:0000:0000:4600:4dff:fe22:abb5 error=-28 hns3 0000:7d:00.0 hns_0: attr path_mtu(1) invalid while modify qp The reason for the error is that the gid being occupied will cause the failure to modify the gid. The gid is occupied by the loopback QP used by free mr. When the mac address is modified, the gid will change. If there is a busy QP at this time, the gid will not be released and the modification will fail. The QP of free mr is created using the ib interface. The ib interface will add a reference count to the gid, resulting in this error scenario. Considering that free mr is solving a bug in HIP08, not an actual business, it is not necessary to use ib interfaces.
