What I mean specifically is the following dependency logic which will
no longer be required:


The patch also brings additional flexibility to users of
distributions. Distros typically ship something like an allmodconfig
so a user can either run openvswitch.ko with all encaps compiled in
or not run openvswitch.ko. With vports as module, a user can blacklist
a certain encap type.

Another advantage is obviously that users can run additional vport
types on top of their distribution kernels.

Is there anything specific that you are concerned with in regard
to this proposed change?
