| | | | | | | | | | | | | | | receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@
* replace the use of ifqueues for most input queues serviced by netisrdlg2015-04-103-32/+13
| | | | | | | | | | | | | | | | | with niqueues. this change is so big because there's a lot of code that takes pointers to different input queues (eg, ether_input picks between ipv4, ipv6, pppoe, arp, and mpls input queues) and falls through to code to enqueue packets against the pointer. if i changed only one of the input queues id have to add sepearate code paths, one for ifqueues and one for niqueues in each of these places by flipping all these input queues at once i can keep the currently common code common. testing by mpi@ sthen@ and rafael zalamena ok mpi@ sthen@ claudio@ henning@
* Use rt_ifa_add(9) and rt_ifa_del(9) to configure MPLS labels.mpi2015-03-261-2/+3
| | | | | | | | | | | | | Since the removal of the link-layer ifa from "struct ifnet" it was impossible to configure MPLS routes on mpe(4). Because just like enc(4), mpe(4) was abusing the link-layer ifa to attach its route entries. So explicitly pass a "glue" ifa to the routing layer. From Rafael Zalamena who discovered this the hardway, thanks! ok claudio@

| | | | | | | | by a pop operation we need to forward the packet to the specified nexthop as is. This is done by calling the interface output routine directly. This is different to the local operation since that one injects the packets into ip_input() via netisr. OK michele

* Rework the way we handle MPLS in the kernel. Instead of fumbling MPLS intoclaudio2010-05-283-82/+138
| | | | | | | | | | | ether_output() and later on other L2 output functions use a trick and over- load the ifp->if_output() function pointer on MPLS enabled interfaces to go through mpls_output() which will then call the link level output function. By setting IFXF_MPLS on an interface the output pointers are switched. This now allows to cleanup the MPLS input and output pathes and fix mpe(4) so that the MPLS code now actually works for both P and PE systems. Tested by myself and michele (A custom kernel with MPLS and mpe enabled is still needed).
