T4240 Rman Doorbell

Contributor II

    In T4240QDS board,I want to use Rman to manage doorbell type packet.

I can send doorbell packet,but the speed is very slow! about 1 s every packets.

while I can receive error packet.I debug my software.

We have test_speed program provided in USDPAA FRA application to measure doorbell type packets transcending speed through SRIO.

After setting up FRA application, please execute the following command  to test the speed.

fra>testspeed [send/receive] [packet length] [packet number] [loop number]

Have a great day,
