From: Klaus D. Wacker Date: Fri, 5 Oct 2007 14:45:44 +0000 (+0200) Subject: qeth: HiperSockets layer-3 interface drop non IPv4 or non IPv6 packets X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bc4b2b497aa61c79e3f3444237a4003a254ea565;p=linux-beck.git qeth: HiperSockets layer-3 interface drop non IPv4 or non IPv6 packets HiperSockets infrastructure (layer-3 mode) supports only IPv4 or IPv6 packets. Sending other packet types disturbs TCP/IP on z/VM, which issues messages about invalid packets. Qeth send routine will detect packet type on sending over a HiperSockets interface (in layer-3 mode) and drop non IP packets. The error and drop count of the interface is incremented.
