Rasool, Nice findings. Thank you for your work. Making ipfw/dummynet work well under higher freq is much needed and very useful. Hans, Does the branch fix (or help) with the problems reported by Rasool? If so, is it possible for you to have a patch that can be applied against -head? Unsure about others but it'd be easier for someone like me to test.= =20 Cheers, Hiren --T4sUOijqQbZv57TR Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQF8BAABCgBmBQJWOVGIXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRBNEUyMEZBMUQ4Nzg4RjNGMTdFNjZGMDI4 QjkyNTBFMTU2M0VERkU1AAoJEIuSUOFWPt/lEMYH/0my9OwMDF8VksN8pVLSaODU i2zQJ5bt0pGWlEVguAVvm9SN99z1DsCOgI8YLmxsIxrhKgK1ner0GeqoXw+D9XxR mXD7Ns7t2eGKpw8xV1rFt42ZfTfCGUUbIAO+vFdYN3MEvMVXITA59jadjgiZFvDP RemXjujDpOqjTJ9Makh5cAeHrCD8RbBRtHcr5QnxCh/PhpS246s2hsVd5UuXdZvh VjdB2Rz4z8P9bofBW4qWxVZL+Ca7zUMXzpLTfYNquSG5/wDnlaOrvr90UB8prEF5 TcJuPWOk3uu9ZOufSTM9gsexN9Mus+/SVKZvhwFLoAKMk7NysGY/pZqv8iGPYzk= =kDV0 -----END PGP SIGNATURE----- --T4sUOijqQbZv57TR--
