[pve-devel] nftables 0.4 and kernel 3.19, still problem with physdevin|out

[Wolfgang Bumiller]

I think Xbriport only ever works on bridge filters, (on current kernels,
too). Is there any reason to put it in the ip tables? You can still
match on `ip saddr`, `ip6 saddr`, `ip6 nexthdr` etc. in bridge filters.

Btw. I find the table syntax much more readable than command lists.
table bridge filter {
  chain forward {
    type filter hook forward priority 0;
    meta obriport vmap { tap115i0: jump tap115i0-OUT, ...
  }
}

(That way it should be atomic and it also ensures the shell doens't
mess with {} braces, hrhr ;-) )
