2017-08-03DHCP Client: receive unicast ACKsNeale Ranns2-8/+80
despite VPP DHCP client setting neither ciaddr nor giaddr and setting the broadcast bit (see RFC 2131 section 4.1) some DHCP servers will still send a unicast DCHPACK. So as not to drop this VPP must have both 1) a receive FIB entry for the OFFERED IP adress and 2) a 'don't drop me because of uRPF' FIB entry for the DHCP server's address.

2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo9-162/+497
Added APIs want_l2_macs_events and l2_macs_event to allow an API client to receive notification events from VPP for MAC learned or aged in L2FIB. Only one API client is allowed for L2 MAC events. The want_l2_macs_events API allow caller to specify MAC learn limit, event scan delay and max number of MACs that can be included in a event message. These parameters should be choosen properly as to not have too many MAC events sent by VPP and overwhelm the API share memory. They can all be left as 0's so VPP will setup reasonable defaults which are: 1000 learn limit, 100 msec scan delay and 100 MACs per event message. If want_l2_macs_events is never called, VPP learning and aging should behave as before except that MAC entries provisioned by API or CLI will not be aged, even if it is not set as static_mac. These non static MACs, however, can be overwritten by MAC learning on a MAC move as a leared MAC. Only learned MACs are subject to aging.

2017-07-18FIB path preferenceNeale Ranns13-62/+647
Paths are given a preference, lowest value is 'best'. Only paths that are up are up contribute to fprwarding - that's unchanged. What's new is that of the path's that re up only those that have the best preference contribute. A poor man's primary and backup. It's not true primary/backup function because the FIB must converge before the lower preference paths are used.

2017-07-10vlib: store buffer memory information in the buffer_mainDamjan Marion3-5/+5
Currently, buffer index is calculated as a offset to the physmem region shifted by log2_cacheline size. When DPDK is used we "hack" physmem data with information taken from dpdk mempool. This makes physmem code not usable with DPDK. This change makes buffer memory start and size independent of physmem basically allowing physmem to be used when DPDK plugin is loaded.
