FYI, for Linux LMDE6 appears to have the best support for the NICs. 2.5Gbit working out of the box at proper speed with in-kernel module, MTU 1500 over vsftpd/lftp with multiple transfers enabled ( lftp -- set mirror
arallel-transfer-count 2 ) or higher number.
For 10Gbit SFP+ ports, I tested the two right-side ports with a 10Gbit DAC and MTU 9000 and got as-expected numbers with iperf3.

As you can see this is a very recent kernel, hopefully they fixed the bugs reported earlier in this thread. I have a proper 2-port 10Gbit SFP+ pcie card on order and 2x 10Gbase-T transceivers so I can connect the Qotom to my ZFS server.
Also have 4x 10Gbit fiber transceivers and will try connecting my 2.5Gbit 4-port and 8-port switches with the SFP+ ports to see if it makes a difference.

PROTIP: You don't have to spend a lot of money if you want to use SAS/SATA enclosure with the Qotom.
^ 5-bay SAS/SATA hotswap enclosure, all you need is a standard PC power supply with 2xMOLEX.
Under $90 at time of posting, and you get a spare bay for drive swaps.
I paired the enclosure with a SAS internal 4-breakout cable to the Qotom and it works just fine:
Currently my pc power supply is also connected to a spare 5-bay hddrack for power-on, but you should be able to get things working with a power supply jump-cable if needed.
