Subject: net/mlx5e: Properly resolve TC offloaded ipv6 vxlan tunnel source address

From: Paul Blakey <[email protected]>

[ Upstream commit 08820528c9d3ff0d0eda047d7ef5ecac2da1ef6c ]

Currently if vxlan tunnel ipv6 src isn't supplied the driver fails to resolve it as part of the route lookup. The resulting encap header is left with a zeroed out ipv6 src address so the packets are sent with this src ip.

Use an appropriate route lookup API that also resolves the source ipv6 address if it's not supplied.
