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. > If, as Jakub suggests, DCCP has no users other than MP-DCCP, and as > such shouldn't be maintained,=C2=A0 FWIW, I agree that in kernel user would help DCCP "de-deprecation" > then are you suggesting that we investigate this license concern to > allow for MP-DCCP to move upstream, or did you have a patch in mind? 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. Cheers, Paolo
