4.5.1.1 EtherType
Here you can choose the ethertype of the TECMP header. Please find more information
about the TECM Protocol in Chapter 6
TECMP [0x99FE]: The header of each logged frame gets the ethertype 0x99FE and the
header is a TECMP header
Legacy Mode [0x2090]: The header gets the ethertype 0x2090. The protocol is very
similar. Some fields have a different name but in general, the functionality is the same.
