[openib-general] IPoIB and lid change

[Michael S. Tsirkin]

Hi, Roland!
One issue we have with IPoIB is that IPoIB may cache a remote node path for a
long time. Remote LID may get changed e.g. if the SM is changed, and IPoIB might
lose connectivity.

One simple way to address this would be to have a list of all
address handles per net device and kill them on an SM change event.

What do you think?
