https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215737 Rodney W. Grimes <rgrimes@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rgrimes@FreeBSD.org --- Comment #11 from Rodney W. Grimes <rgrimes@FreeBSD.org> --- (In reply to P Kern from comment #10) I believe that issue of not being able to forward pacekts through a VM using vmx(4) with MTU >4K is that on the receive side the incoming packets are chunked up into n * 4k pages and these do not pass through the forwarding c= ode correctly. This in effect frag's the jumbo frame as it tries to traverse the router, and I do not think the code is up to that task, nor is that a desirable situation. --=20 You are receiving this mail because: You are the assignee for the bug.=
