I don't think so. On Arbel, ib_mthca uses the entire upper part of the 32bit word as the sequence counter. Is SINAI_OPT is set, the sequence counter is in bits 25-31 (17-24 seem to be reserved, and bit 3 is mirrored to bit 23 - this is what adjust_key seems to be doing). If SINAI_OPT is not set, the sequence counter is in bits 17-31, and adjust_key is a no-nop. So when the sequence counter overflows, it doesn't spill into any reserved bit. At least that's how I read the code.
