I'm confused by the documentation I've found on host stack access using netmap. The documentation says: "Packets generated by the host stack are extracted from the mbufs and stored in the slots of an input ring, similar to those used for traffic coming from the network. Packets destined to the host stack are queued by the netmap client into an output netmap ring, and from there encapsulated into mbufs and passed to the host stack as if they were coming from the corresponding netmap-enabled NIC."
Does this refer only to packets generated internally by the host stack, or can they be triggered by user-level code? Suppose I put an interface into netmap mode (eg eth1) with the NIOCREGIF flags indicating NETMAP_SW_RING. Is there any way to then open a socket, bind it to the IP address of that interface and then try to issue a connect via that interface? Do I instead have to craft the entire connect packet (ie a TCP SYN) and send it via a Netmap ring? _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
