    @laforge this calculation seems to be correct due to how unsigned subtraction and conversion to signed works. This is also how the before() and after() functions are implemented in the linux kernel.

    Checked with a unit test in gdb:
    448 diff = cur_seq - last_seq;
    (gdb) print last_seq
    $4 = 65535
    (gdb) print cur_seq
    $5 = 1
    (gdb) n
    453 if (diff <= 1)
    (gdb) print diff
    $6 = 2
