From b758858c5ceb1b30ae7d04dea6c74821bd7c7d69 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 26 Jun 2014 10:26:22 -0700 Subject: [PATCH] net: bcmgenet: do not set packet length for RX buffers Hardware will provide this information as soon as we will start processing incoming packets, so there is no need to set the RX buffer length during buffer allocation.
