[ns] change LL layer for a node

[Yan Yu <yanyu@catarina.usc.edu>]

Hi, there,
  I want to change the link layer for a node, use a link layer I developed
myself other than the LL in ns, I am wondering how can I do it for a
regular node other than a node on the LAN? (I can specify the link
layer when creating a LAN..)
  since I am told before that node-config only works for wireless node,
but I am using wired node..

btw, I tried 
$ns node-config  -llType *MylinkLayer* 
and use [$ns node] to create a new node after that, but it does not
work.. it still use LL in ns..

does anyone have any idea how I can change a link layer for a wired node?

Thanks,
yan
