Subject: [PATCH] mlx5: Fix wqe size parameter in wqe signature calculation
|
|
|
|
[ Upstream commit 8cde184624d192f7cd61247eec92a3a9b4ba7c7f ]
|
|
|
|
WQE signature calculation requires passing the size of the WQE as a
|
|
parameter.
|
|
|
|
Current code passes the qpn_ds field as the WQE size which is wrong.
|
|
Fixing to extract from the qpn_ds the WQE size in bytes and use it for
|
|
the signature calculations.
|
|
|
|
Fixes: 8c4791ae2395 ("libmlx5: First version of libmlx5")
