Min Hu (Connor) Sept. 17, 2020, 8:23 a.m. UTC
This commit adds testpmd capability to query and config FEC
function of device. This includes:
- show FEC capabilities, example:
	testpmd> show port 0 fec capabilities
- show FEC mode, example:
	testpmd> show port 0 fec_mode
- config FEC mode, example:
	testpmd> set port <port_id> 0 <auto|off|rs|baser>

	where:

	auto|off|rs|baser are four kinds of FEC mode which dev
	support according to MAC link speed.
