From cb36a1dbaf29babb536bd10d0ff3ff35ca57bfa3 Mon Sep 17 00:00:00 2001 From: Kingwel Xie Date: Wed, 20 Mar 2019 03:45:47 -0400 Subject: ip6-rewrite: bug fix buffer->error in dual loop error should be recorded in buffer so that process-error-punt can handle them correctly Per Damjan's comments, move counter to under else clause of last error0==NONE check. Both v4 and v6 are changed.
