I have a 9.2 system running in a VMware VM which receives the following
message at startup which I've never seen before. The VMware network driver
in use is VMXNET 3; the VMware tools daemon is running:

kernel: TCP: ens192: Driver has suspect GRO implementation, TCP performance
may be compromised

There does not appear to be any actual networking or performance impact so
far, but obviously this will be used eventually for higher-volume servers,
so any performance impact is important. Does anyone have more info on this
issue?
Thanks.....Nick
