This commit adds testpmd capability to query and config FEC

- show FEC capabilities, example:

- show FEC mode, example:
testpmd> show port 0 fec_mode
- config FEC mode, example:
testpmd> set port <port_id> fec_mode auto|off|rs|baser
where:
auto|off|rs|baser are four kinds of FEC mode which dev
support according to MAC link speed.

Hi Connor,
Sorry for catching this late, but there is a new 'rte_eth_link_speed_to_str()'
API in the ethdev, which may enable removing above global 'eth_speed_name' array
[1].
I will proceed with this patchset, but can you please send an increamental patch
to use the 'rte_eth_link_speed_to_str()'?
If it comes before the next-net pulled I can squash it, if not it can stay as
individual patch.
Thanks,
ferruh
