Hi I am using the ubuntu system(5.0.0 kernel) to test the hip08 NIC port,. When I modify the perr mac1 to mac2,then restore to mac1, it will cause the gid0 and gid 1 of the roce to be unavailable, and check that the /sys/class/infiniband/hns_0/ports/1/gid_attrs/ndevs/0 is show invalid. the protocol stack print will appear.

I wonder if the _ib_cache_add_gid() is defective in 5.0 kernel? Thanks Lijun
