Looking for feedback on change to iflib and transmit queuing

Hi, I have a Phabricator review here that I was hoping to get some feedback on: https://reviews.freebsd.org/D34742 In short, there's already some functionality in current and 13.1-RELEASE that allows a driver to pick a TX queue for a packet, but this extends that support to have iflib do some

Could you reply to that issue with what you've found? Though, as far as I can recall, igb(4) devices are not supposed to do the iflib reset talked about in the bug, so I wouldn't expect to see a link flap on those. - Eric On Fri, Nov 6, 2020 at 12:48 PM mike tancsa wrote: > On 11/6/2020 2:17

Re: kernel module code coverage

I'm reviving an ancient thread, but is Bullseye truly dropping FreeBSD support? Do you have a link to something that shows that? I still see a FreeBSD tarball in their download archive page for the newest version of their tool, which seems to be 8.16.5. - Eric On Thu, Aug 8, 2019 at 12:08 PM

Re: problem building dev/e1000

ifdi_if.h is a system generated interface file that network drivers that depend on iflib use. It's generated from ifdi_if.m in sys/net. My guess is that you don't have "device iflib" defined in your kernel configuration. em(4) depends on iflib in FreeBSD 12/13, and with r343617, iflib is now

Re: Hyper-V FreeBSD-CURRENT Guest and SR-IOV Pass Through

None of the Intel networking drivers on FreeBSD support Hyper-V. Could you try "Discrete Device Assignment" instead? Create the VFs on the host somehow, then pass them through to the VMs? That looks like it might work for the FreeBSD VF drivers. - Eric On Mon, Oct 22, 2018 at 12:11 PM Michael

Re: [VBox] Extreme slow UDP performance between host and guest

Did you use the "-b" option to set the bandwidth it uses for UDP? It defaults to 1Mb/s, which is close to what you're seeing. Plus, I think the recommendation is that you use iperf3, anyway, and I don't think it has this quirk. On Thu, Sep 1, 2016 at 2:06 AM Howard Su

Are you still getting the -100 errors when trying to load the VF driver? I've tried SR-IOV on a system here, and I can confirm that traffic stops passing on the PF interface when you create a VF interface. That didn't used to happen, so I'm investigating why that is right now. On Wed, Feb 24,
