It happens when fetching Android project files by "repo sync" through ssh.
More logs:
Bad packet length 38201470.
Finished discarding for 10.65.180.40 port 29418^M
packet_process_incoming: Connection to 10.65.180.40 port 29418: message authentication code incorrect^M
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
I realized the error message like "Bad packet length 230911661." comes from ssh source file packet.c thus tried different SSH version but the issue is still there.
$ ssh -V
OpenSSH_7.6p1 Ubuntu-4ubuntu0.1, OpenSSL 1.0.2n 7 Dec 2017
...
$ ssh -V
OpenSSH_7.5p1 Ubuntu-10, OpenSSL 1.1.0g 2 Nov 2017
In addition, I've tried workaround for NIC as:
$ sudo ethtool -K enp3s0 rx off
...
$ sudo ethtool -K enp3s0 rx off tx off
but this doesn't work either.
Here is the Network card information:

Do you have a reason to think this is a firmware issue? Otherwise the bug should probably be against the linux package.
