-Subject: [PATCH] brcmfmac: Update msgbuf read pointer quicker.
-
-On device to host data using msgbuf the read pointer gets updated
-once all data is processed. Updating this pointer more frequently
-allows the firmware to add more data quicker. This will result in
-slightly higher and more stable throughput on CPU bounded host
-processors.
