Description
If 'dom_capability' not in port_info_dict, insert 'N/A'
Motivation and Context
Currently, some vendors are using custom transceiver info parsers which do not yet provide the
dom_capability
field in the results ofget_transceiver_info()
. However, PR #72 introduced storing this value to State DB under the assumption that it would always be present. On platforms where this value is not present, it would cause xcvrd to crash (see issue: sonic-net/sonic-buildimage#6978).This change will prevent a crash if it is not present, and will in turn save
'N/A'
as thedom_capability
value in State DB.How Has This Been Tested?
Tested on one affected platform.
