Subject: [PATCH 4.9 22/66] net/mlx5: Fix wrong size allocation for QoS ETC TC regitster

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

------------------

From: Shay Agroskin <shayag@...lanox.com>

[ Upstream commit d14fcb8d877caf1b8d6bd65d444bf62b21f2070c ]

The driver allocates wrong size (due to wrong struct name) when issuing
a query/set request to NIC's register.

Fixes: d8880795dabf ("net/mlx5e: Implement DCBNL IEEE max rate")
