2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-1/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-09-03Improve L2FIB PDR/NDR performance (VPP-963)John Lo1-1/+1
1. Limit MAC entry update per l2-learn call to reduce update burst when wall clock advance to the the next minute so all MAC time stamps are behind current time needing update. 2. Optimize l2-learn node fast path code sequence. 3. Invalidate cache_key when update MAC entry. 4. Change L2 learn hit counter to L2 learn hit-update counter. 5. Increase L2FIB table memory size to 512MB to fit 4M entries 6. Set MAC learn limit at 4M entries Change-Id: I3075ee8fb59645a56850126bac2e3e6d341cef4d Signed-off-by: John Lo <loj@cisco.com>
2017-08-22Increase default MAC learn limit and check it in learn-update pathJohn Lo1-1/+1
1. Increase default MAC learn limit from 1M to 8M entries. 2. Check MAC learn limit in MAC learning update path. 3. Allow disable of want_l2_macs_events to set MAC learn limit 4. Other minor cleanups Change-Id: I62438440937b5fa455e16f4a2e4d910277753395 Signed-off-by: John Lo <loj@cisco.com>
2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo1-0/+5
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.

2017-03-28Implement MAC Flush for BD or Interface from the L2FIBJohn Lo1-0/+1
Allow non-static MACs in the L2FIB which is associated with an interface or a bridge domain (BD) be flushed. MAC flush are initiated automatically when an interface is removed from a BD or when a BD is deleted. MAC flush can also be invoked manually via the following CLI: l2fib mac-flush interface <if-name> l2fib mac-flush bridge-domain <bd-id> Change-Id: Ie33243622834810a765f48ebcd22bdb8e8fc87a4 Signed-off-by: John Lo <loj@cisco.com>
