-Subject: [PATCH] ath10k: remove shadow copy of CE descriptors for source
- ring
-
-For the messages from host to target, shadow copy of CE descriptors
-are maintained in source ring. Before writing actual CE descriptor,
-first shadow copy is filled and then it is copied to CE address space.
-To optimize in download path and to reduce d-cache pressure, removing
-shadow copy of CE descriptors. This will also reduce driver memory
-consumption by 33KB during on device probing.
