can not ues ib_write_bw

[a-c-dream]

my problem is same to #72. when I run ib_write_bw in pod, I get a error as follows:

[root@mofed-test-cx5-bond-pod2 /]# ib_write_bw -d mlx5_0  -F --report_gbits

When I set the master to the rdma NIC of one of these two sets of servers it works fine, can anyone explain why?

macvlan master interface needs to be the netdevice of the RDMA capable NIC. it uses that to generate GID IIRC.
