From 828d27ea0edb97280a0164041a286973fa74b5a2 Mon Sep 17 00:00:00 2001 From: Matus Fabian Date: Tue, 21 Aug 2018 03:15:50 -0700 Subject: bihash: add support for reuse of expired entry when bucket is full (VPP-1272) Applications such as NAT that dynamically create entries require these entries to expire after some time. Bihash user can now lazily delete expired entries. When inserting and bucket is full, expired entry is overwritten.
