using netgear we had stability issues to nodes running vm's when mode 6 was
used. mode 3 is stable.
switch to switch mode 6 works here.
I posted to netgear managed switch forums. [their support has been be
great]. and have much some useless and other useful detail there. i am
not a kernel network expert , however this looks like a setting at
/etc/network/interfaces vmbr* setting . or a kernel thing.
