IFF_PROMISC bug?

[Jeff Garzik <jgarzik@xxxxxxxxxxxxxxxx>]

Gentlemen,

When I run tcpdump, /sbin/ip shows PROMISC, but /sbin/ifconfig does not.

This is on recent RedHat and MDK boxes, at least.  Alan Cox also noted
that "ifconfig eth0 promisc" causes /sbin/ifconfig to show PROMISC.

Somewhere, interface flags are not being propagated/shared correctly?

This is on a 2.4 kernel.  /sbin/ip uses netlink to get the flags
(ifi_flags), and /sbin/ifconfig uses SIOCGIFFLAGS.

        Jeff
