From 6631c5c9b0c3698f3977caf5694e8ece6a36f48b Mon Sep 17 00:00:00 2001 From: Andrey Shvetsov Date: Thu, 15 Sep 2016 16:19:06 +0200 Subject: [PATCH] staging: most: hdm-dim2: double size of DBR buffer This patch increases the size of the asynchronous and control DBR buffers in the Tx path to twice the max. message size. This patch is needed to increase the throughput for big messages.
