Date: Mon, 4 Aug 2014 12:33:45 -0700 From: Haiyang Zhang <haiyangz@...rosoft.com> To: davem@...emloft.net, netdev@...r.kernel.org Cc: haiyangz@...rosoft.com, kys@...rosoft.com, olaf@...fle.de, jasowang@...hat.com, linux-kernel@...r.kernel.org, driverdev-devel@...uxdriverproject.org Subject: [PATCH net-next] hyperv: Increase the buffer length for netvsc_channel_cb() When the buffer is too small for a packet from VMBus, a bigger buffer will be allocated in netvsc_channel_cb() and retry reading the packet from VMBus. Increasing this buffer size will reduce the retry overhead.
