Hi,
uhd_usrp_probe reports that I should raise my send_frame_size &
recv_frame_size arguments.
USRP Manual, transport notes, report to change them in device or
stream arguments.
Anyone knows how to change these settings in the NIC?
I have a 10 Gb MLNX NIC and just upgraded my Ubuntu from 14.04 to
20.04. I am pretty sure I had some of these optimizations in the NIC
using ethtool? Anyone remembers what these optimizations were?
TIA

These are device arguments -- part of UHD:

Now, IN ADDITION, to actually support those, your NIC must have its MTU
changed to support the larger frame sizes -- you can just use the
Network device manager
in the GUI to change this. Normally, though, a 10GB NIC will have a
larger MTU by default.
