This will have some really great changes for performance and standardization that have been bouncing around inside of various FreeBSD shops that have been collaborating with Matt Macy over the last year. This will implement multiple queues for certain em(4) devices that are capable of such things and add some new sysctl's for you to poke at in your monitoring tools. Due to limitations of device registration, igbX devices will become emX devices. So, you'll need to make a minor update to your rc.conf and scripts that manipulate the network devices. UPDATING will be bumped to reflect these changes. MFC to stable/11 will have a legacy implementation that doesn't use IFLIB for compatibility reasons. A documentation and man page update will follow in the next few days explaining how to work with the changed driver. sean bcc net@ current@ re@ --tp6mSFJQkh8sAaD7HtXUsahMv6ilcehdm-- --XJakuSKaqHqTnjkCXkf2062ux6Nr1763p Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQGTBAEBCgB9FiEEuq1GMucSHejSCZfdEgHvyh5yfmQFAlhvDIBfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEJB QUQ0NjMyRTcxMjFERThEMjA5OTdERDEyMDFFRkNBMUU3MjdFNjQACgkQEgHvyh5y fmTZlggAwzQ4B/dxwOB5ID0jnpLPw5EiZ3lRUo0lu2QG8dBhGZLIGqWlRbJ/YQYE yPxmngf3c2n/y/eM1BRNFvuumy58VvcSRM2csFJAxMYHNHhIaz4u6IVhjj6Cn+Sl S+/SQMY3481iLIYWDwI7t9BTAlfXEBxIq65a8NW0JR1B9vT5UpohtTJb8Nvd1bRi AEZ7XHsNdhV6L2ichQCghUvF/ncIB9H3YZ8XlIpgjCHJtML9BRjB5ntBKAwLB4+/ KEW1AyhUtjLG8muHkYvqawn0EA948sf7q3hYDDCwW2tJKFX0WRGcOseZNi/mifah zAjf5HcBlqEMC6EPhoD5LxhOdH9n2w== =eg1J -----END PGP SIGNATURE----- --XJakuSKaqHqTnjkCXkf2062ux6Nr1763p--
