Subject: net/mlx5: fix leak on Tx queue creation failure
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b689b00dd253356567c4d95f55921ce6c0e87d80;p=dpdk.git

net/mlx5: fix leak on Tx queue creation failure

In Tx queue creation, there are two validations for the Tx
configuration.

When one of them fails, the MR btree memory was not freed what caused a
memory leak.

Free it.
