This is also applied to MTU=2K size as well since ppage size is greater
than 2K on different platforms is not guaranteed. This skb issue is an
independent effort with supporting MTU=4K. We need to address non-CM skb
issue in general. Let's have a simple patch to enable MTU=4K support first
in 2.6.24, then address non-CM skb issue in a different patch next, Do you
agree?

Thanks
