--- Comment #2 from smi...@nimnet.asn.au ---
Rats, ae@ beat me to it .. i << 32 is of course 0.
But not just sbin/ipfw .. also in /sys/netpfil/ipfw/ip_fw2.c:
case O_DSCP:
{
uint32_t *p;
uint16_t x;
[..]
/* DSCP bitmask is stored as low_u32 high_u32 */
if (x > 32)
match = *(p + 1) & (1 << (x - 32));
else
match = *p & (1 << x);
}
