[dpdk-dev] [PATCH] net/mlx5: fix nested flow creation error

[Matan Azrad]

 From: Xueming Li 
> If xmedata mode 1 enabled and create a flow with RSS and mark action, there
> was an error that rdma-core failed to create RQT due to wrong queue
> definition. This was due to mixed flow creation in thread specific flow
> workspace.
> 
> This patch introduces nested flow workspace(context data), each flow uses
> dedicate flow workspace, pop and restore workspace when nested flow
> creation done, the original flow with continue with original flow workspace.
> The total number of thread specific flow workspace should be
> 2 due to only one nested flow creation scenario so far.
> 
> Fixes: 8bb81f2649b1 ("net/mlx5: use thread specific flow workspace")
> Fixes: 3ac3d8234b82 ("net/mlx5: fix index when creating flow")
