These limits have been recently updated, from 8 to: - 64 for the subflows and accepted add_addr - 255 for the MPTCP endpoints These modifications validate the new limits, but are also compatible with the previous ones, to be able to continue to validate stable kernel using the last version of the selftests. That's why new variables are now used instead of hard-coded values.
