net: fix regressions for generic-XDP
Thanks to Brandon Cazander, who wrote a very detailed bug report that
even used perf probe's on xdp-newbies mailing list, we discovered that
generic-XDP contains some regressions when using bpf_xdp_adjust_head().
First issue were that my selftests script, that use bpf_xdp_adjust_head(),
by mistake didn't use generic-XDP any-longer. That selftest should have
caught the real regression introduced in commit 458bf2f224f0 ("net: core:
support XDP generic on stacked devices.").
To verify this patchset fix the regressions, you can invoked manually via:
cd tools/testing/selftests/bpf/
sudo ./test_xdp_vlan_mode_generic.sh
sudo ./test_xdp_vlan_mode_native.sh
