I have a box with 4x of the i210 (but that shows up as igb(4)) I have one of the i217LM nics in this machine, but it is used for video production so it isn't running BSD at the moment. --=20 Allan Jude --2f2SSrPjuFSuSmS2eFCX3345hMHjvtrgk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQIcBAEBAgAGBQJUDed+AAoJEJrBFpNRJZKfkaAP/0U9hD4UGOzddyjivjUvRSo+ BCpnKHG8uk9O5KjAvlDam7BdwhKETjZuHD8FzYfwVmjmNT1aPaAgxo3iW1lRxB4r mvXpLzNjXZB1+dIb2hf1QrwMW8DndBLOlY3h7U0pr7tg1csRudJYXEKazpmWTYpI oT51+ze8Hj9lcwrSIJTdQ5j0u9k5fkc3my4pj9LyuYTKXtRMB+NV59QZhnNAm1hX IwP+cs6OGEOc9aZG7Ars2UhYSngr3B/GgA9ZRRK7FLG+XbC3+LL6vaHsXrT9uRxi rQ2MLZKUDJQoZvpitjuzm6y9xbgH3Stn1vL/E2WCeCDGLF8C2O9HI30vmy7qHBV7 J3RJpMciBZa28NCWqtgWxAKfBO1fPdZz/k9Wk49WqrhryFcDJcDtKuvhdXMXlyzX q75VBbiITMkYAiXDx/t4aOLZc/ma3qOcNrqh99Zp4DV76tgpWMw9i6Scdt7kspc0 kV+dY0FmocuaH7V1idyGagEA8UFkXtlLtxuKarn18WYtkZUjWAoBBDs1L1Y+x+xF 4Uhhlq8YQKOKKGShxpXRBi1S/MLKyYfpK/vpZi9feXwso3h6b71e16/zeWxG2TB9 k61RCa4PzZLU7/XhiEGTMIdU4AsEcbG7xDAlti0GrkYQHw1qu9iBzoPcak7lFdNc AFH57XP0HYL8VZUDzNF0 =nAM5 -----END PGP SIGNATURE----- --2f2SSrPjuFSuSmS2eFCX3345hMHjvtrgk--
