This commit fixes the issue of optics not detected error while running sfputil show eeprom command. The root casuse was the value of port index from port_config.ini for fan out scenario. The port index should be starting from 0 and not 1. Platform cpld registers are assuming the port numbers to start from 0 (lowermost bit), sfputils.py uses this port number in get_presence function. Since the indexing passed is wrong the optics was not detected and gave SFP EEPROM not detected message. Signed-off-by: Harish Venkatraman <[email protected]>

port index is used to identify the front panel port, if z9100 front panel port start from 1, then port index should start 1. |

This commit fixes the issue of optics not detected error while running sfputil show eeprom command. The root cause was wrong port_index in fan out scenarios. Earlier fix of changing the port_config.ini is reverted and changes made in z9100 platform specific sfputil.py file. The port number is decrement and tested for both 100G and 50G fanout cases. Tested for the following show commands and test was succesful show interfaces status, show interfaces transceiver eeprom, show interfaces transceiver lpmode, show interface tranceiver presence.

This commit fixes the issue of optics not detected
error while running sfputil show eeprom command. The root
casuse was the value of port index from port_config.ini for
fan out scenario. The port index should be starting from 0
and not 1. Platform cpld registers are assuming the port
numbers to start from 0 (lowermost bit), sfputils.py uses this
port number in get_presence function. Since the indexing passed
is wrong the optics was not detected and gave SFP EEPROM not
detected message.
