It adds error correction information to data packets at the transmit end, and uses the error correction information to correct the bit errors generated during data packet transmission at the receive end. This improves signal quality but also brings a delay to signals. This function can be enabled or disabled as required. This patch adds FEC support for ethdev.Introduce ethdev operations which support query and config FEC information in hardware.

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