1
On Proxmox VE 6.0 (kernel 5.0.18-1-pve, ixgbe 5.1.0-k) an Intel X520-DA2 exposed ens1f0/ens1f1 but any inserted third-party SFP+ module produced failed to load because an unsupported SFP+ or QSFP module type was detected, and the driver had to be reloaded to detect module changes at all. Hardware involved: Intel X520-DA2, third-party SFP+.
- Hardware: Intel X520-DA2
- Transceivers: third-party SFP+
- Form factor: SFP+

Proxmox staff suggested loading ixgbe with allow_unsupported_sfp=1; the poster added a /etc/modprobe.d snippet, rebuilt the initramfs and the modules came up.
