Subject: [PATCH 3.18 016/150] iwlwifi: mvm: update values for Smart Fifo

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

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

From: Emmanuel Grumbach <emmanuel.grumbach@...el.com>

commit b4c82adcba8cb4b23068a6b800ca98da3bee6888 upstream.

Interoperability issues were identified and root caused to
the Smart Fifo watermarks. These issues arose with
NetGear R7000. Fix this.
