Dell Intel Ethernet Network Adapter X710-T4L 2.5GB and 5GB Negotiation

Hardware Questions and Recommendations

As a follow up, the Intel brand X710-T2L link modes advertise as expected. This is the 2 port card vs. the 4 port. I don't know if the issue is with Dell brand X710 cards in general or just the one I tested.

That’s great news. I ordered the intel one last week just waiting for it to get delivered. You were able to get 2.5gb working in openwrt as well?

Yes, the Intel brand X710-T2L is working for me with openwrt at 2.5gb.

nice! do you still have the dell card? I wonder if something like this would work.

ethtool -s eth0 advertise 0x1800000001028

seems like the x550 has the same problem but someone created a package to start advertising the 2.5 and 5 speeds

I don't have the dell card, but this would have been interesting to try.
