Try adjusting the MTU as well to 1500

FYI
ifconfig

Can you post the output of *ifconfig* on your system?

Thanks!
I am learning to use RFNOC to integrate a baseband. So I used PyBOMBS to create
the environment. The automatically installed UHD version is as follows
uhd_find_devices
[INFO] [UHD] linux; GNU C++ version 7.4.0; Boost_106501;
UHD_3.15.0.git-19-g7e1b567d

Found the offending commit and reported the issue. It also looks like
adding *recv_frame_size=1476* explicitly to the device arguments cleared
things up on my N310 running 3.14.1.0. Let me know if this does / doesn't
work for anyone.

Normally Intel controllers have better performance but even a RealTek chip
should have no problem at those data rates.

Actually my pc’s Ethernet card chip is from Realtek.
I’ve tried all possible MTU sizes of auto, 1000, 1500, 2000, and up to 9000.
Always the same errors.
Is it the inherent problem with the Realtek chip?
If that, is there any workaround? eg. Changing the default Linux driver,
or the last solution,
