Unfortunately, there multiple issues at play here: The FreeBSD em(4) driver under 10.3+ has this bug, and the Intel 7.6.2 driv= er fixes this on 10.3. But the Intel driver does not fully work under 11.0 --= it has issues with netmap(4) (e.g. using Suricata) there. The link issue in particular also manifests in several VM deployments that = we heard of through OPNsense, where widespread emulation of e1000 is an integr= al part of daily operation and required to be reliable. The only fix there wa= s to install the Intel driver, but obviously this doesn't fully work on 11.0 anymore. So we were hoping to see some progress in either: Getting the FreeBSD 10.3+ regression ironed out, and/or Seeing an Intel driver bump for reliable netmap(4) operation under 11.0. Bottom line is can we help in any way to speed this up? Thanks, Franco --=20 You are receiving this mail because: You are the assignee for the bug.=
