I therefore question you assessment of the situation. Is it really RealTex NICs that are substandard or is the FreeBSD supplied driver at fault? It is my belief that this is 1) something that deserves to be studied in-dept, and 2) it isn't going to happen, at least not at the retail level. --=20 Jerry --Sig_/sbq1aV+JdoXNDQjm8l+RiUH Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEIQb/tTwl6I1ueEVtOHMGOIfexWQFAl70sTMACgkQOHMGOIfe xWSeAQf/X1aPBNUge6dqINWzbRXaLXNrhr5W7Yunn5r1pSHZKBc7rKmwLJ4x92oB v4oP9wcBRJbZ2CC0WTgQPc8MBICw4tVoBRJiQ6bh47OGIzH49aURmErmDcWY4EhU +DyPDCTIIZzHRuo0Tv+j9PWIiAGRgyhdingIP0kO6Nmnct7Yd2sw1C5XAkbjflVi h+EBMNHebF+Pf2/0wnqWxxYPaZYmugWBgjfDbp6zoOt977uKiR9fEtMgo+W42hXn 9T/2BJwFvbwzUVJOu/v6SzktiwlSaV3cmsoG+cWU/CnxX8cJx5iSf153NY8onk8Q RyC/iVn1lQlV5lFIquUegJDaVtrQpA== =jnM3 -----END PGP SIGNATURE----- --Sig_/sbq1aV+JdoXNDQjm8l+RiUH--
