Date: Thu, 26 Jun 2014 10:26:22 -0700 From: Florian Fainelli <f.fainelli@...il.com> To: netdev@...r.kernel.org Cc: davem@...emloft.net, Florian Fainelli <f.fainelli@...il.com> Subject: [PATCH net 3/3] 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.
