Dear all, 

I hope this is the right place to ask, if not please advise me where to go.

I have a new Dell machine with both an Intel on-board ethernet controller 
([8086:15f9]) and an additional 2-port extension card ([8086:1521]). 

The second adaptor, a "DeLock PCIe 2xGBit", worked fine as far as I could 
see with Linux 5.10.59, but fails to initialize with Linux 5.14.9.

Any advice on how to proceed? Willing to test patches and provide additional debug info.

Thanks,
