I agree with you that it's not necessary for Ethernet/IP traffic. The point is that this isn't really Ethernet/IP traffic, it's InfiniBand/IP traffic. And there it *is* necessary. An argument can be made that the core code shouldn't assume Ethernet/IP and should support either Ethernet/IP or InfiniBand/IP. --=20 Doug Ledford GPG KeyID: 0E572FDD --JF5xngKsujOmFUMfksFEO3j6iHGnSmHH9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJV+ZgfAAoJELgmozMOVy/djmIQAJZiyGySyu9fkt5xxymWKemA 1J/wS4rVUBTOgji1QAv9Vwnniz6yUBYkvql0Ut/JUOYDKMh+CWUI71hQblvRAYGe 3psJNiuanWNhvXWN78/fy6MFecYNDp+Usd4oIr40KplhNvcYAC3XD6FnUie3slX7 9mCYSUf8NA5bc9u6Sziycuf5+RCBn1Q9S5vgUTZWuq13g26y9CUzLKP+J/hCUGV5 E3fD8Csf5nGV91rGDutOqQaCuOGsehhm2mdpIoXk4cJLKAHmlJUDS6+86qkgD/0j n1Da/Nw7aM5gofMoNRIXqhVE5xPsf2Y6yo7Tn0ABl8xZkS+zj4GOPrMD98t3uhKM hpawuSpyKt40nCmJ+MFV1vheUadGCCI5x3VXRJP/nyVitLllL8DhCkqk/GpCqpRf azozCbAC3fDuJ4erjwcXU+YjOuCxYP9cg4VVnljo8UkjyNN7zQyy45U51N8rdjGM o/blOa2/vP4cdlL+0MCd7Cwyuf6YlwqryC1+xGe/v28M22gSw3gO7Hg+Bt5VX43u VoAmeN/v6GoOLlAia9OixJYK4LmQCJcUW2OtoMoKLYVoLlQZe3v3awH+OitD9rqh VOJYmqmslaipRl8t/K/8I2R1vt35o93zZRZSW/LHl68RUBBxU6XI/hCNbADjUZpS DpqwcZeJNbolOmmIvVfB =xP9I -----END PGP SIGNATURE----- --JF5xngKsujOmFUMfksFEO3j6iHGnSmHH9-- -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
