no traffic flows on latest ten64 branch #18

Closed dch closed 1 year ago

dch commented 1 year ago

src 5f6b8b38dfebacb69aad59122e86d18484e7e3c1 tip of ten64 branch.

Not quite sure how to characterise this bug. I see inbound IP traffic but nothing makes it out an interface, nor across between interfaces. pf is running, route appears to select the correct interface. Just nothing gets out.

I'm not sure whether it's the same issue, but I can't do any traffic after booting until I replug the network cables. If I just unplug them and immediately plug in, traffic starts working.

dsalychev commented 1 year ago

@pkubaj Sounds like a different issue. Could you report it as a separate bug? I'm going to close this one because almost all of the changes in the ten64 branch have found its way into https://github.com/mcusim/freebsd-src/tree/dpaa2 one and it's a correct branch to test.
