After further testing, I can confirm that this issue persists with supported Intel SFPs (Intel FTLX8571D3BCV-IT).
As for the changeset introducing this issue - we had failure reports with previous DPDK versions, probably related to LSE handling, but these weren’t properly investigated. The change in 16.11 which calls get_phy_capability too early in initialization stage might have alleviated the issue making it easier for us to detect and confirm.
Best regards,
Christos Ricudis.
