[Update atlantic/aquantia lan drivers to 6.1.13 +]

I have received my Intel X540-T1 and did some testing. The Intel NIC was surprisingly recognized as 1GbE by unRAID, transfer was stable. With the same cable, the Aquantia was recognized as 5GbE, transfer was not stable with frequent loss of connection. Ends up the cable was the problem even though it should handle 10GbE speed (cat6 15m, might be damaged). With another cable, both NIC were recognized as 10GbE. With the Intel NIC, I got max 3GbE stable speed. With the Aquantia, I got 10GbE stable speed (so far). Both were tested with 9000 MTU. I will now use the Aquantia and see how it behaves, especially regarding stability. I'm not sure how temperature might affect the NIC performance now that the unRAID case has been closed and put back where it belongs. But it seems like the Aquantia is a better NIC with unRAID in my network configuration (unexpected result). The X540 chipset being a rather old chipset, I'm not sure if it is expected to do full 10GbE speed in all scenarios.

 

That does not solve the issues I had in the past with onboard Aquantia NIC with my Windows machine (frequent loss of connection). If that happens again, I'll test the Intel NIC in one my Windows machines. I will probably rewire everything with better cables when I found the courage.

 

Conclusion: hope is not lost for those of us with Aquantia NIC (at least with Linux machines).

I have the same problem. At best link is reported as 5G but that changes sometimes to 2.5G and I've got some heavy link dropouts. I've got two other Aquantia NIC in Windows machines (onboard NIC) and I've got issues with all of them. I'm switching to Intel NIC for all my machines. High temperature as well as poor driver might explain this behaviour.
