I executed successfully the following instructions:

  mplsadm2 -A -O gen:100:eth2:ipv4:192.168.1.18
  mplsadm2 -L eth0:0
  mplsadm2 -A -I gen:50:0 -i 
ds2exp:0x3f:0x2e:1:0x0a:2:exp2tc:1:0x2e:2:0x0a:fwd:key:2

for Paul : if you execute a command for ds2exp and then a command for exp2tc, 
only the latest instructions will be set

for James : after executing the last command, it appears on the screen "In 
Instr: Device not configured" even if the instructions are set correctly.
Moreover you should correct in mpls_proc.c (case exp2tc) to avoid that 
information like exp(5)->tc(ffff) are printed in /proc/net/mpls_*
