There's no way for the target to return credits through responses? I
agree that we should implement the full SRP spec in the initiator but it
seems unfortunate to force both an initiator and target upgrade to fix
what really appears to be a target bug. This means anyone running a
pre-2.6.34 kernel won't be able to use the SCST SRP target reliably.
