Subject: [PATCH 05/12] iwlwifi: pcie: Add support for Bz Family
Precedence: bulk

From: Matti Gottlieb <matti.gottlieb@intel.com>

Add support for different combinations of Bz
and CRFs.

Note: As of now we do not know the exact values
for ltr_delay and xtal_latency, so for now use the
worst case scenario values until the actual values
are clarified.
