From 848b47c70ecfb0bb45636c5c806391848e2878f9 Mon Sep 17 00:00:00 2001 From: John Lo Date: Thu, 4 Jan 2018 16:39:42 -0500 Subject: Unify/cleanup usage of hash_set/unset_mem by tunnels (VPP-1117) Move the functions hash_set_key_copy() and hash_unset_key_free() which are dupilicated in various tunnel support code modules to hash.h as hash_set_mem_alloc() and hash_unset_mem_free() to be used by all.
