From e9f6499965c64109e296f61e3aa7fd91f9f2233c Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Thu, 1 Dec 2016 18:03:05 +0100 Subject: [PATCH] net: mvneta: Do not allocate buffer in rxq init with HWBM For HWBM all buffers are allocated in mvneta_bm_construct() and in runtime they are put into descriptors by hardware. There is no need to fill them at this point. Suggested-by: Marcin Wojtas Signed-off-by: Gregory CLEMENT Tested-by: Marcin Wojtas Signed-off-by: David S.
