VPP-68: L2 Rewrite: Support for chained classify tables
The classifying capabilities are pretty limited if only a single table can be used. This patch adds support for chained classify tables to L2 Rewrite feature. Change-Id: Ib678fe2028f17b441adb75d85bf3e31185e42c59 Signed-off-by: Pierre Pfister <ppfister@cisco.com>
