A little background. The prism2 series of wireless ethernet cards are capable of operating in true promiscious mode, capturing raw 802.11 frames. When it's doing this, the driver prepends a special monitoring header onto the packet with useful information.=20 Since the v0.1.6 release of the driver, this was handled via NETLINK broadcasts.. but that's Bad(tm). Instead, the next version (0.1.14) of the driver will support raw capture using the PF_PACKET interface, which means that it'll need its own arp type for libpcap to recognize and handle the special headers. (without the header, it sends standard ARPHRD_IEEE80211 frames)=20 libpcap/ethereal/etc already have dissectors for this special header, so all that's left is to define a fixed arp type. So, I humbly submit this patch for inclusion. Thanks! --=20 Solomon Peachy pizzaATfucktheusers.org I ain't broke, but I'm badly bent.
