From 0c0c43705c89c1705669c75396a811482dcb6679 Mon Sep 17 00:00:00 2001 From: Olivier Matz Date: Fri, 13 Feb 2015 10:22:50 +0100 Subject: [PATCH] i40e: fix offloading of outer checksum for IPIP tunnel When offloading the checksums of ipip tunnels, m->l2_len is set to 0 as there is no tunnel or inner l2 header. Since this is a valid value remove the test. By the way, also remove the same test with l3_len because at this point, it is expected that the software provides proper values in the mbuf. It should avoid a test in dataplane processing and therefore slightly increase performance.
