SFP 1G di Intel X710 (pfSense, ixl) gagal dengan unqualified module sampai optiknya di-recode jadi Intel

Di Protectli Vault 6 dengan port SFP+ Intel X710 (ixl0/ixl1), SFP 1G EZConn ETB43315-7S34-FR menunjukkan no carrier. Log-nya berisi Invalid advertised speed; valid flags are: 0x06, ixl1_set_link: Error getting phy capabilities -37, aq error: 8 dan Link failed because an unqualified module was detected!. Memaksa media (ifconfig ixl1 media 1000baseLX mengembalikan Operation not supported), utak-atik sysctl advertise_speed, tunable hw.ixl.unsupported_sfp=1, dan beberapa merek SFP 1G lain semuanya gagal, sementara modul 10G Cisco LR link normal. Upgrade firmware NIC dari 6.1.49420 ke 9.40 membuat modulnya terdeteksi tapi tetap tidak ada link.
