[dpdk-dev] [PATCH v3 03/14] acl: remove of unused enum value

[Konstantin Ananyev]

Removal of unused enum value (RTE_ACL_CLASSIFY_NUM).
This enum value is not used inside DPDK, while it prevents
to add new classify algorithms without causing an ABI breakage.

Note that this change introduce a formal ABI incompatibility
with previous versions of ACL library.
