[Bug 404708] Re: Broadcom BCM5906M ethernet adapter (tg3) hangs under heavy tcp load (bittorrent) when generic segmentation offload (gso) is in use

I can confirm this bug on a Lenovo Ideapad S9E(NIC BCM5906M). The
problem was noticed for the first time when using the Ideapad as a
pulseaudio network sound server. Turning off gso alone did not solve the
problem for all traffic patterns. Setting the MTU to 1000 AND turning
off gso solved the problem for all tested traffic patterns.

Thanks for posting a solution!
