2.enet transceiver: BradR-Reach BCM89811

 

Problem description:

In my project, I config enet communication with PC. When  I ping ip commond from PC to MCU every 1000ms, the  packets round-trip speed is 1000ms, but when  I ping ip commond from PC to MCU every 100ms, the  packets round-trip speed is 100ms. why the packets round-trip speed is different? is that any incorrect config of mcu enet module?
