Description Masachika ISHIZUKA 2000-12-23 11:10:01 UTC

	It is good working with 1mbit/s shaping when start up, but
	I want to modify shaping speed with the following command.

	# ipfw pipe 1 config bw 10mbit/s

	Then no packet was transmitted at all. The packets are queued
	as follows and dropped.

	# ipfw pipe show
	q00001: weight 5 pipe 1   50 sl. 14 queues (64 buckets) droptail
	    mask: 0x00 0x0000001f/0x0000 -> 0x00000000/0x0000
	BKT Prot ___Source IP/port____ ____Dest. IP/port____ Tot_pkt/bytes Pkt/Byte Drp
	  2 ip           0.0.0.1/0             0.0.0.0/0      2060   199376 50 4852 1928

	Is there any way to modify shaping speed of active pipes ?

  Very sorry.

  I miss typed 10mbit/s.
                 ~
'ipfw pipe 1 config bw 10Mbit/s' can be modified to 10Mbit/s.

State Changed
From-To: open->closed

i assume the problem had to do with either a typo in the config 
command, or a known and fixed problem related to spl() masks. 
Either way, the PR seems not relevant anymore.
