[openib-general] Re: [PATCH 1 of 3] core: static rate encoding changesupport

[Waleri Fomin]

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.
