I've updated sys/dev/e1000 at svn R311849 to match Matt Macy's work on IFLIB in the kernel. At this point, the driver deviates from Intel's code dramatically and you now get to yell directly into the freebsd-net@ megaphone for things that I may have broken. man page updates are coming up next. Please let us know if this revision has made things better, worse or none-of-the above on whatever Intel Gigabit NIC you happen to have lying around. sean On 01/05/17 20:18, Sean Bruno wrote: > tl;dr --> igbX devices will become emX devices >=20 > We're about to commit an update to sys/dev/e1000 that will implement an= d > activate IFLIB for em(4), lem(4) & igb(4) and would appreciate all folk= s > who can test and poke at the drivers to do so this week.
