As Kuniyuki noted, a relevant record of contributions to netdev would
help/be appreciated/customary before proposing stepping-in as
maintainer of some networking components.

FWIW, I agree that in kernel user would help DCCP "de-deprecation"

IMHO solving the license concerns and move MP-DCCP upstream (in this
order) would be the better solution. That would allow creating the
contributions record mentioned above.

FTR MPTCP is already there, perhaps there is some possible convergence
between the 2 protocols.
