Hi,
    I build iproute2 tools (1.946a) by armeb-linux-uclibc 
(from http://buildroot.uclibc.org,  XScale big endian).

but when I run "mpls nhlfe add key 0" I got error

RTNETLINK answers: Invalid argument


and "mpls nhlfe show" got strange error

"mpls labelspace add dev eth0 labelspace 0" got error

But other tools like iptables, ip work well.
I ever built tools with arm (little-endian) and it works find.
Could anyone kind give me some hints ?

Best regards,
