Jakub Kicinski suggested following patch:

W=1 C=1 GCC build gives us:

net/bridge/netfilter/nf_conntrack_bridge.c: note: in included file (through

../include/linux/netfilter_bridge.h): include/uapi/linux/if_pppox.h:
153:29: warning: array of flexible structures

It doesn't like that hdr has a zero-length array which overlaps proto.
The kernel code doesn't currently need those arrays.

PPPoE connection is functional after applying this patch.

LGTM, can you send this one directly to netdev@vger.kernel.org?

Its not netfilter related so it feels wrong to apply it, even though I
agree with it :-)

No need to resend the rest of this series.
