1. We tested the IET functionality on the TDA4 board, and the configuration is as follows:
And we send data through iperf, and at the same time we send data through sockets in user space, Iperf commands are as follows
iperf3 -c 192.168.100.20 -u -b500M -l1472 -t300
iperf3 -s
2.测试结果如下：
1): We sent data from user space via socket(priority (1-7)), then through "ethtool -s eth0 | grep iet" command found that "iet_tx_frag" counter in growth, but when we stop socket data, will not grow
But when we send data through socket with priority 0, this counter is not incremented
2）We send data over the socket with priority1 and find that "tx_pri1" counter increases as well, We send data over the socket with priority2 and find that "tx_pri2" counter increases as well, as well as the socket data of
other priorities
