Hi, This is a resend of my dec 12, 2010 post. It appears that I forgot to Cc to Linux Netdev list. The reason for this patch follows. A second one follows in next message. [PATCH] [ROSE] rose AX25 packet routing improvement FPAC AX25 packet application is using Linux kernel ROSE routing skills in order to connect or send packets to remote stations knowing their ROSE address via a network of interconnected nodes. Each FPAC node has a ROSE routing table that Linux ROSE module is looking at each time a ROSE frame is relayed by the node or when a connect request to a neighbor node is received. A previous patch improved the system time response by looking at already established routes each time the system was looking for a route to relay a frame. If a neighbor node routing the destination address was already connected, then the frame would be sent through him. If not, a connection request would be issued. The present patch extends the same routing capability to a connect request asked by a user locally connected into an FPAC node. Without this patch, a connect request was not well handled unless it was directed to an immediate connected neighbor of the local node. Implemented at a number of ROSE FPAC node stations, the present patch improved dramatically FPAC ROSE routing time response and efficiency. Signed-off-by: Bernard Pidoux <f6bvp@free.fr>
