From 02ee0658362d3713421851bb7487af77a4098bb5 Mon Sep 17 00:00:00 2001 From: Stanislav Fomichev Date: Mon, 22 Apr 2019 08:55:52 -0700 Subject: bpf/flow_dissector: don't adjust nhoff by ETH_HLEN in BPF_PROG_TEST_RUN Now that we use skb-less flow dissector let's return true nhoff and thoff. We used to adjust them by ETH_HLEN because that's how it was done in the skb case. For VLAN tests that looks confusing: nhoff is pointing to vlan parts :-\ Warning, this is an API change for BPF_PROG_TEST_RUN! Feel free to drop if you think that it's too late at this point to fix it.
