SCTP_RESET_STREAMS carries a flexible array of u16 stream IDs, but the
optlen clamps treat USHRT_MAX as a byte count and then multiply
sizeof(__u16) by the fixed header size.
That caps the copied and validated option buffer at about 64 KiB, which
rejects valid requests containing more than about half of the u16 stream
ID range.
