MarsSeed [1] filed a deletion request for iproute-mptcp [2]: Orphaned package. Seems it has not had a tagged release since 2018. [a] It is called an iproute-extension, but it is actually a forked iproute2 with some addon functionality. Arch repo carries the current upstream iproute2. So I recommend deleting this abandoned package.
