Subject: IB/mlx4: Don't update QP1 in native mode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d24d9f43384b5933867a5786934e130efa8b5c92;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

IB/mlx4: Don't update QP1 in native mode

For native functions (non-SR-IOV), there's no reason to update
the smac_index, as QP1 is a GSI QP.
