Subject: [PATCH 01/21] iwlwifi: set correct single/dual stream mask
Date: Fri, 16 Apr 2010 14:52:18 -0700 [thread overview]
Message-ID: <1271454758-14351-2-git-send-email-reinette.chatre@intel.com> (raw)
In-Reply-To: <1271454758-14351-1-git-send-email-reinette.chatre@intel.com>
From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Even the initial single/dual stream values will be overridden later when
issue link quality command; but still make sense not to use hard-code
value during initialization. Single/Dual stream mask are used to indicate the
best antenna for SISO/MIMO; different NIC has different tx antenna
configuration; so the parameter need to based on the valid tx antenna.
1x2 device: single tx antenna available, only SISO is valid
configuration, but still need to set up MIMO configuration, so set it up
with antenna A & B as default.
2x2 device: two tx antenna available, dual_stream will use both valid
antenna.
3x3 device: three tx antenna available, skip the first antenna and
choice the second and third antenna for dual_stream.
