From db32919005d81a375093936a1f625f2d08c2d299 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Sat, 28 Oct 2017 19:46:21 +0800 Subject: [PATCH] ip_vti: remove the useless err_count check in vti_xmit Unlike ipip and gre, ip_vti never uses err_count in vti4_err, so no need to check err_count in vti_xmit, it's value always 0.
