Michael, Roland,
There can be a situation where the link/port speed gets changed for example from 12x to 4x...
Does OpenIb/IPoIB take care about this new configuration, i.e. does stack reconfigure all qps by sending modify_qp with the new link speed
to inform hca about the change or should hca take care about reconfiguring the qps?
Thanks,
Waleri

Please apply the static rate patch and post a patch for ehca to
support the updated API.
