tl;dr --> igbX devices will become emX devices We're about to commit an update to sys/dev/e1000 that will implement and activate IFLIB for em(4), lem(4) & igb(4) and would appreciate all folks who can test and poke at the drivers to do so this week. 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@
