Improve L2FIB PDR/NDR performance (VPP-963)
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>
