This is true, this may change (the same is for min rate/MTU). Then there may be just basic range check like this: if (rate_required < IB_MIN_RATE || rate_required > IB_MAX_RATE) error...; But it is likely useless - later we are checking port's physical capability to support such rate). > The realizability is when the port joins not when the group is created. > This is significant for the precreated groups (as other groups are > created when the first port joins). > > Is min rate/MTU needed for anything ? Currently it is used when the rate is not requested. Also for cases when the rate is requested as greater than specified value. There is such check: if (rate_requested >= min_ca_rate) error... - the same problem I think.
