[mpls-linux-devel] MPLS-linux testing with netperf

Hold the fire hoses.  I thought someone had stated mpls-linux had roots 
in VLAN code so I tested netperf using VLAN tags.  It turns out netperf 
has issues with VLAN tagged packets as well.  aka the source system 
terminates the send with the same "Interrupted system call" error 
message when sending vlan tagged packets to a target.

This is very disappointing, as netperf has been a valuable perf tool.  I 
guess exploration into netperf more is warranted.
