Johannes This is dependent on the NIC Driver. Chelsio's have a option to prioritize "slow-protocols" into a dedicated queue. The iflib drivers I believe in 12-STABLE and newer have this ability as well. Non iflib nics like Solarflare do not have any way to prioritize this and 11-STABLE does not have it at all. For the Chelsios you need to set hw.cxgbe.rsrv_noflowq=1" in /boot/loader.conf or use kenv to set it before loading the module. --- Mark Saad Lucera Financial Infrastructures, LLC msaad@lucera.com ________________________________________ From: owner-freebsd-net@freebsd.org <owner-freebsd-net@freebsd.org> on behalf of Johannes Lundberg <johalun0@gmail.com> Sent: Thursday, February 4, 2021 3:56 PM To: freebsd-net@freebsd.org Subject: LACP BPDU packets priority? *This email originated from outside the Firm* Hi We're experiencing unstable lacp lagg and not seeing BPDU packets coming to the switch we when expect them to. Can anyone answer what is the priority of those packets? Could it be that they are not being sent from the FreeBSD host because they are stuck in outgoing queue? Please cc me since I'm not subscribed.
