I guess it is:
set port <port_id> fec_mode <auto|off|rs|baser>

Can you please update the testpmd documenatation for the new commands?

Also can add the new command to the --help output? ('cmd_help_long_parsed()')

<...>

Can you please update the help string as:
"set port <port_id> fec_mode auto|off|rs|baser"

'<>' is to define the variable name, like in '<port_id>' you expect numbers like 
0,1,2 .. but 'auto|off|rs|baser' are keywords, not variables.
