QUIC: additional limit for probing packets.
RFC 9000, 9.3. Responding to Connection Migration:
An endpoint only changes the address to which it sends packets in
response to the highest-numbered non-probing packet.
The patch extends this requirement to probing packets. Although it may
seem excessive, it helps with mitigation of reply attacks (when an off-path
attacker has copied packet with PATH_CHALLENGE and uses different
addresses to exhaust available connection ids).
