I understand, Everyone would like not to have out of tree kernel
modules in dpdk repo.

Is it possible to
a) move existing or new out of tree module or
b) libraries can be used by another project or
c) DPDK device drivers binary FW repo like Linux kernel FW etc(The
ones connected to dpdk)

add it in https://www.dpdk.org/hosted-projects/

and use tools like "https://gerrit.googlesource.com/git-repo/"[1] for
development and distribution case

git-repo: tools used by android for a similar situation.
