[PATCHv2 0/2] Resolve packet capturing on macvlan lowerdev

[David Ward <david.ward@ll.mit.edu>]

Change in v2: Declare variables in basic block before other code appears

The following two patches address situations where macvlan interfaces on 
the same lowerdev are created inside separate containers/namespaces, and 
traffic between these interfaces needs to be captured by monitoring the 
lowerdev outside the containers/namespaces using tcpdump or Wireshark. 
The only case where this doesn't work now is for unicast frames when the 
macvlan interfaces are operating in bridge mode; this fixes that case.

Should the dev_queue_xmit_nit function be renamed to something more 
meaningful, which would indicate its role in sending outgoing frames to 
AF_PACKET sockets? It is currently a misnomer: this function used to be 
invoked by dev_queue_xmit, but that is no longer the case.

Thanks,

David
