Merge branch 'selftests-forwarding-fix-br_netfilter-related-test-failures'

Aleksei Oladko says:

====================
selftests: forwarding: fix br_netfilter related test failures

This patch series fixes kselftests that fail when the br_nefilter
module is loaded. The failures occur because the tests generate
packets that are either modified or encapsulated, but their IP
headers are not fully correct for sanity checks performed by
be_netfilter.
