Hi Greg, To be able to apply the last patch without conflicts in v6.6, 4 other clean-up patches are needed. These patches mainly replace existing code with helpers to reduce code duplication. It looks interesting to backport them to ease future backports. I had a few conflicts in mptcp_lib.sh, because some of the new helpers have been backported recently, but not all: so I had to place them between others. Note that these patches are the same the ones I sent earlier for v6.7, no other conflicts.
