3. Basic ping pong test:
a. Server side: ibv_rc_pingpong -g 0 -d bnxt_re<x> -i 1
[root@dhcp-10-13-107-210 ~]# ibv_rc_pinpong -g0 -d bnxt_re0 -il
local address: LID 0x0000, QPN 0x000094, PSN 0x390112, GID fe80::210:18ff:fead:1fa0
remote address: LID 0x0000, QPN 0x000095, PSN 0xe00732, GID fe80::210:19ff:fead:1fa0
8192000 bytes in 0.01 seconds = 4410.53 Mbit/sec
1000 iters in 0.01 seconds = 14.86 usec/iter
b. Client side: ibv_rc_pingpong -g 0 -d bnxt_re<x> -i 1 <ServerIP>
[root@dhcp-10-13-107-210 ~]# ibv_rc_pinpong -g0 -d bnxt_re0 -il 10.0.0.50

14.2.4.1 Performance Test (perftest) Package
The perftest package is a collection of tests written over uverbs intended for use as a performance micro-benchmark. The
tests are used for tuning as well as for functional testing. The server-side IB server and the client-side IB client must be run.
The perftest package contains the following bandwidth and latency benchmarks:
 ib_send_bw
 ib_send_lat
 ib_write_bw
 ib_write_lat
 ib_read_bw
 ib_read_lat
1. The IB test tool help commands are viewed using the following -h parameter in the command:
# ib_send_bw -h
2. Verify that the IP and RoCE node is up on both sides with the following command:
ifconfig InterfaceName ; ibv_devices;
The Interface Name is the name of the Ethernet interface.
3. Run ib_send_bw on both sides with the following commands:
