[PATCH net 0/2] mptcp: 32-bit sequence number improvements

MPTCP-level sequence numbers are 64 bits, but RFC 8684 allows use of
32-bit sequence numbers in the DSS option to save header space. Those
32-bit numbers are the least significant bits of the full 64-bit
sequence number, so the receiver must infer the correct upper 32 bits.

These two patches improve the logic for determining the full 64-bit
sequence numbers when the 32-bit truncated version has wrapped around.

Paolo Abeni (2):
  mptcp: fix bad handling of 32 bit ack wrap-around
  mptcp: fix 32 bit DSN expansion
