Subject: [PATCH net-next] ip_vti: remove the useless err_count check in vti_xmit
Date: Sat, 28 Oct 2017 19:46:21 +0800 [thread overview]
Message-ID: <b28eef283ea7622e74a930cc708489fa9c1139c7.1509191181.git.lucien.xin@gmail.com> (raw)
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.
