I don't really know what the metadata stuff is for but nothing looks
alarming so:

That said some of the patches look like they should rather go to net.
e.g. 4, 6, 11.. why not?

In simple words: the NIC steering pipeline knows to look into the
packet fields in addition to that it can also provide and match on
"metadata" such as, origin function, dest function/port if already
determined, and some other well known hw registers..
