[PATCH 5.4 150/340] RDMA/mlx5: Use the correct obj_id upon DEVX TIR creation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yishai Hadas <yishaih@xxxxxxxxxx>

[ Upstream commit 8798e4ad0abe0ba1221928a46561981c510be0c6 ]

Use the correct obj_id upon DEVX TIR creation by strictly taking the tirn
24 bits and not the general obj_id which is 32 bits.

Fixes: 7efce3691d33 ("IB/mlx5: Add obj create and destroy functionality")
