3.13.11-ckt32 -stable review patch.  If anyone has any objections, please let me know.

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

From: Marcin Wojtas <mw@semihalf.com>

commit dc1aadf6f1e7609590fadf7a0252413732289b2e upstream.

A value originally defined in the driver was inappropriate. Even though
the ingress was somehow working, writing MVNETA_RXQ_INTR_ENABLE_ALL_MASK
to MVNETA_INTR_ENABLE didn't make any effect, because the bits [31:16]
are reserved and read-only.

This commit updates MVNETA_RXQ_INTR_ENABLE_ALL_MASK to be compliant with
the controller's documentation.

unit")
