System: NetBSD Tandoor.DSG.Stanford.EDU 1.2B NetBSD 1.2B (DSG_4K.prof) #5: Mon Jan 20 17:38:50 PST 1997 jonathan@Cup.DSG.Stanford.EDU:/aga/n1/src/NetBSD/IP-PLUS/src/sys/arch/i386/compile/DSG_4K.prof i386


>Description:
	Netstat -I <interface> prints netmasks, but on
	an i386 the netmasks printed are wrong.

>How-To-Repeat:

Configure network interface on an i386 with non-octet aligned
 subnet masks.
Compare the results of ifconfig -a, and netstat -I for each interface.

The following is from a machine with two interfaces with 
netmasks of 255.255.255.128. One interface is on a class B net,
the other on net 10:

>From ifconfig  -a:

	Tandoor# ifconfig -a
	ep1: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
	        inet 171.64.79.100 netmask 0xffffff80 broadcast 171.64.79.127
	vassa0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
	        inet 10.0.0.1 netmask 0xffffff80 broadcast 10.0.0.127

>From  netstat -i:
