[PATCH] PPC64: iSeries virtual ethernet transmit errors

From: Stephen Rothwell <sfr@au1.ibm.com>

This patch stops the iseries_veth driver trying to send every packet to too
many logical partitions.  Consequently, the number of transmit errors falls to
(about) zero from a very large number.  This should also improve performance a
bit as the driver is no longer doing 31 extra skb_clone()s and skb_free()s for
each packet.
