Subject: [PATCH 3.0.y 0/3] rtnetlink: Fix problem with buffer allocation

These patches fix the problem that interface information including many
VFs is too large for the 4K buffers used by glibc and other clients.
This breaks many network services.

The first of these ('rtnetlink: Compute and store minimum ifinfo dump
size') went into 3.1 and has also been included in SLE11 SP2.  The
second and third were acked by David Miller and included in 3.2.34.

I've applied and briefly tested these changes in conjunction with a
backport of the sfc driver to SLE11 SP3.

Ben.
