Re: [mpls-linux-devel] mpls-linux on 64 bit kernel

[Ahsan T. <ahs...@gm...>]

Hi,

So disabling debug everything is ok :). So i have another question: Below is
a debug trace
for one ping as seen on an MPLS enabled router. While sending an MPLS packet
the
MAC header (bold lettering) is incomplete, but while recieving an MPLS
packet the
MAC header is complete. Is this expected behaviour or am I interpreting it
wrongly ?

Thanks

Ahsan
