>Description:
If IP_PORTRANGE_HIGH is set as a socket option, it will set INP_PORTHIGH on inp_flags.  However, since INP_ONESBCAST is the same value and is also set in inp_flags, this will cause some problems with UDP checksums on these sockets.

This was fixed previously in kern/87306, however it was reintroduced in kern/99558

>How-To-Repeat:
Call setsockopt() with IP_PORTRANGE_HIGH on a UDP socket.  Send traffic through socket.
