Subject: [PATCH net 0/2] bpf: Fix bpf_redirect to an ipip/ip6tnl dev

Hi,

This patch set fixes a bug in bpf_redirect(dev, flags) when dev is an
ipip/ip6tnl.  The current problem is IP-EthHdr-IP is sent out instead of
IP-IP.

Patch 1 adds a dev->type test similar to dev_is_mac_header_xmit()
in act_mirred.c which is only available in net-next.  We can consider to
refactor it once this patch is pulled into net-next from net.

Thanks,
-- Martin
