Subject: [PATCH 3.13 117/163] iwlwifi: increase DEFAULT_MAX_TX_POWER

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

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

From: Eliad Peller <eliad@...ery.com>

commit 22d059a5c7c5de61e53c88e30b65e55fbfd91e91 upstream.

The chip is able to transmit up to 22dBm, so set
the constant appropriately.
