hi im developing the driver for ksz8851snli, as of now i need to ping between the microcontroller to the pc and vice versa.

as per the icmp protocol when hit an ping command in cmd terminal iam getting 66bytes of data but as per the standard i have to get 64bytes of data, iam not getting 2 bytes extra why? i gone through the datasheet but i didnt get why iam getting 2 bytes extra,

https://ww1.microchip.com/downloads/en/DeviceDoc/KSZ8851SNL-Single-Port-Ethernet-Controller-with-SPI-DS00002381C.pdf

while iam pinging from mc to pc the mac address1st byte of data is missing this is i observed in wireshark

what are the analyzers i can use to debug the ethernet protocol
