    Merge branch 'tcp-re-enable-acceptance-of-fin-packets-when-rwin-is-0'

    Simon Baatz says:

    ====================
    tcp: re-enable acceptance of FIN packets when RWIN is 0

    this series restores the ability to accept in‑sequence FIN packets
    even when the advertised receive window is zero, and adds a
    packetdrill test to guard the behavior.
