Here is some interesting info that I could not explain.

Why would I get S’s at 6.25Msps boggles my mind. This is the
192.168.30.2 address.
On a hunch, try dropping the MTU on your host PC to 8000, and retrying.
Also, try running the
"benchmark_rate" example, at various --tx_rates to see where it
starts running into trouble.
Then on the USRP PC (I think you called it a SOM), keeping mind this
is a 2974, with IP 192.168.40.2 address. Remember this is an internal
switch.

Notice NO U’s for 100Msps.
*While doing this, I noticed some odd behavior.* With Tx running on
40.2 (the USRP PC), I could not start a test on 30.2 (on the server).
30.2 would give an error
Error: LookupError: KeyError: No devices found for ----->
Empty Device Address
Also doing this: uhd_usrp_probe
[INFO] [UHD] linux; GNU C++ version 11.3.0; Boost_107400; UHD_4.4.0
Error: LookupError: KeyError: No devices found for ----->

They should run independently?
The radio can only support a single session at a time. Trying to run
two sessions from two different host computers
is absolutely not possible.
