if_ipending flags ==> if_flags


From: Joerg Sonnenberger <joerg@xxxxxxxxxxxxxxxxx>
Date: Thu, 15 Apr 2004 17:24:06 +0200

Hi all,
the attached patch moves IFF_PROMISC and IFF_POLLING into ifnet.if_flags
where they belong. It also adjust the ioctl code to use if_flags for the
lower and higher word. Some of the uses were definitely buggy.

I'll commit this tomorrow, if noone objects.
