Public bug reported:
I am using a Thunderbolt 3 Pro Dock with a built in Aquantia 10 GBase-T
NIC (atlantic).
The issue is that during boot it only detects the interface as 5 GBe, as seen
in dmesg:
enp11s0: atlantic: link change old 0 new 5000
This prevents the interface from establishing a connection. With Ubuntu
21.04 and previous versions this issue didn't exist.
I found a couple workarounds for this problem:
1. Enable Thunderbolt Security (User Authorization or Secure Connect) in the
BIOS. This prevents the computer from suspending however, so this workaround
isn't feasible.
2. Run sudo rmmod atlantic && modprobe atlantic and the NIC will connect at 10
GBe without issues as seen below:
atlantic 0000:0b:00.0 enp11s0: atlantic: link change old 0 new 10000
From the obervations above, I draw the conclusion that the module gets
loaded too early with Thunderbolt Security disabled and should happen at
a later point in time.
