RSS_UDP_IPV4_EX?

[Robert N. M. Watson]

My recollection here is (quite) hazy, as it's been a while, but it's likely that this was a transcription error. The set of hash types was largely modelled on what Chelsio offered in the T3 (if I recall), and also what was documented in the Microsoft RSS white paper, so it may be worth taking a look at those sources to see if something makes itself obvious.

(There do seem to be some odd variations in hashing types supported by various NICs -- e.g., hashing but with different hash algorithms in certain generations of cards, etc, so it also wouldn't surprise me if it did correspond to something real. Clearly the comment is not good enough to explain that, if so!)
