There are 64 QSFP+ modules supported in qfx5210 platform. EEPORMs will be
mapped under /sys/bus/i2c/devices/[25-88]-0050/ sysfs directory.
FEC should be turned on for SR4 optics and should be turned off for LR4
optics.
FEC should be turned on for 100G SR optics and should be turned off for
100G LR optics. If the optic is changed, please update the entry and
reload the configuration. If the FEC mode is not set as per the optic
type the port may not link up or work properly.
As an example, see this configuration for FEC for 100G SR4 optics in
/etc/sonic/config_db.json
