Dear Linux folks,
Plugging in Dell GBIC S28-10G-25G-SR-85C (M14MK) [1] into an Intel
Ethernet Controller X710 for 10GbE SFP+ [8086:1572], Linux 6.12.49 logs:
i40e 0000:5e:00.1: Rx/Tx is disabled on this device because an
unsupported SFP module type was detected.
i40e 0000:5e:00.1: Refer to the Intel(R) Ethernet Adapters and
Devices User Guide for a list of supported modules.
Please find more information at the end of this message. Other Intel
devices also have problems with this GBIC, and it works with a Broadcom
device [2].
Kind regards,
Paul
