[spp] [PATCH 19/23] spp_vf: add flag for classifier table

[x-fn-spp at sl.ntt-tx.co.jp]

From: Hideyuki Yamashita <yamashita.hideyuki at po.ntt-tx.co.jp>

Add a flag to check if any of MAC address is registered to the
classifier table. This flag is set to 0 if no entries, or 1 if one or
more entries are registered.
