Adds host electrical interface IDs 152-155 from SFF-8024 Rev 4.14 Table 4-5 (EEI-*-RTLR-* at 106.25 GBd/lane) so LRO application advertisements decode instead of falling through to Unknown. Signed-off-by: Bobby McGonigle <bobby@nexthop.ai>

Description
Adds the four LRO (linear-receive optics) AppSel host electrical interface IDs introduced in SFF-8024 Rev 4.14 Table 4-5 to
sonic_platform_base/sonic_xcvr/codes/public/sff8024.py:EEI-200G-RTLR-1EEI-400G-RTLR-2EEI-800G-RTLR-4EEI-1.6T-RTLR-8These are the 106.25 GBd/lane siblings of the 53.125 GBd
EEI-*-RTLR-*-S/Lcodes 144-151 that are already in the table. Values transcribed from SFF-8024 Rev 4.14 (published 2026-06-04), Table 4-5, page 27.Nothing else changes: no
MODULE_MEDIA_TYPE/ media-interface entries are touched, andCmisApi.LPO_HOST_ELECTRICAL_INTERFACE_IDSis deliberately left alone as LRO is not LPO, and codes 144-151 aren't in that list either. In a future PR I'll ad something similar to the CmisAPIMotivation and Context
Without these entries, a module advertising an LRO application in its AppSel table decodes to
Unknowninget_application_advertisement()and everything downstream of it (sfputil,TRANSCEIVER_INFO, xcvrd application selection).How Has This Been Tested?
Static verification only — no LRO module on hand:
ast.literal_eval, confirmed no duplicate keys, and 152-155 resolve to the names above.One pre-existing discrepancy spotted while cross-checking, not fixed here
to keep this diff to the requested change:
SM_MEDIA_INTERFACE[147]is'800G-FR4-LPO', but Rev 4.14 Table 4-8 lists code 147 (0x93) as400G-FR4-LPO. Can fix in a follow-up if desired.
