Is this possible to set the FEC mode on a qlnxe interface? I have plugged a=
non officiall CISCO 100G DAC on the HPE Eth 4x25Gb 1p 620QSFP28 Adptr" car=
d (817762-B21) but I get the following on freebsd side:
```

Any hint is welcome=C2=A0[:)]=C2=A0It seems It should work if I can the sam=
e mod eon both side. Just changing the FEC on the mikrotik side didn't work=
. Is this normal to not have an option like on others drivers that allow me=
to set the FEC mode during booting?
Let me know,
