Message-Id: <1406050268-13329-1-git-send-email-_govind@gmx.com> Date: Tue, 22 Jul 2014 23:01:05 +0530 From: Govindarajulu Varadarajan <_govind@....com> To: davem@...emloft.net, netdev@...r.kernel.org, ben@...adent.org.uk Cc: ssujith@...co.com, benve@...co.com, Govindarajulu Varadarajan <_govind@....com> Subject: [PATCH net-next 0/3] enic: Add support for rx_copybreak The following series implements rx_copybreak. dma_map_single()/dma_unmap_single() is more expensive than alloc_skb & memcpy for smaller packets. By doing this we can reuse the dma buff which is already mapped. This is very useful when iommu is on. The default skb copybreak value is 256. When iommu is on, we can go much higher than 256. All the drivers that supports rx_copybreak provides module parameter to change this value. Since module parameter is the least preferred way for changing driver values, this series adds ethtool support for setting rx_copybreak.
