[PATCH 4.9 067/271] iw_cxgb4: use tos when finding ipv6 routes

[Greg Kroah-Hartman]

From: Steve Wise <swise@xxxxxxxxxxxxxxxxxxxxx>

[ Upstream commit c8a7eb554a83214c3d8ee5cb322da8c72810d2dc ]

When IPv6 support was added, the correct tos was not passed to
cxgb_find_route6(). This potentially results in the wrong route entry.

Fixes: 830662f6f032 ("RDMA/cxgb4: Add support for active and passive open connection with IPv6 address")
