[PATCH 4.11 25/84] net/mlx5e: Fix min inline value for VF rep SQs

From: Greg Kroah-Hartman
Date: Mon Jul 03 2017 - 10:04:29 EST

4.11-stable review patch. If anyone has any objections, please let me know.


From: Chris Mi <chrism@xxxxxxxxxxxx>

[ Upstream commit 5f195c2c5cba60241004146cd12d71451d6b0fc4 ]

The offending commit only changed the code path for PF/VF, but it
didn't take care of VF representors. As a result, since
params->tx_min_inline_mode for VF representors is kzalloced to 0
(MLX5_INLINE_MODE_NONE), all VF reps SQs were set to that mode.

This actually works on CX5 by default but broke CX4. Fix that by
adding a call to query the min inline mode from the VF rep build up code.
