Subject: [PATCH] Build break on ppc64 for 2.6.21-rc7-mm2

Hi

 When compiling 2.6.21-rc7-mm2, I encountered this error.

make[2]: *** [drivers/net/ehea] Error 2
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2
=================================================

Since code is not compatible with struct sk_buff change, we have this error. 
Below patch should fix this problem. Please let me know your comments on 
this.
