Hi netdev,
quick question: is there a recommended setup to get a send-only packet
socket? I've been reading net/packet/af_packet.c up and down and don't
see an explicit way, so I ended up binding to ("lo", ETH_P_LOOP)
instead. (Nothing special about ETH_P_LOOP, I just grabbed a random
value tha

Hi all,
this is an update on the earlier "[RFC net-next] VPLS support". Note
I've changed the subject lines on some of the patches to better reflect
what they really do (tbh the earlier subject lines were crap.)

Add a NDA_VPLS_WIRE attribute to the FDB dump if we have dst metadata
that is indicative of a VPLS pseudowire. This is really helpful for
debugging.

Hi all,
triggered by Amine posting VPLS support earlier, this is what I had in
mind on my end. You may note the patches share some bits, this is
because both series are derived from hacks I did at 33C3 in December
2016.
This patchset is different in the following ways:

This wires up the neccessary calls for VPLS into the MPLS forwarding
pieces. Since CONFIG_MPLS_VPLS doesn't exist yet in Kconfig, it'll
never be enabled, so we're on the stubs for now.

This implements holding dst metadata information in the bridge layer,
but only for unicast entries in the MAC table. Multicast is still left
to design and implement.
