2010-06-15netdev:bfin_mac: reclaim and free tx skb as soon as possible after transferSonic Zhang
SKBs hold onto resources that can't be held indefinitely, such as TCP socket references and netfilter conntrack state. So if a packet is left in TX ring for a long time, there might be a TCP socket that cannot be closed and freed up. Current blackfin EMAC driver always reclaim and free used tx skbs in future transfers. The problem is that future transfer may not come as soon as possible. This patch start a timer after transfer to reclaim and free skb. There is nearly no performance drop with this patch. TX interrupt is not enabled because of a strange behavior of the Blackfin EMAC. If EMAC TX transfer control is turned on, endless TX interrupts are triggered no matter if TX DMA is enabled or not. Since DMA walks down the ring automatically, TX transfer control can't be turned off in the middle. The only way is to disable TX interrupt completely.

2008-10-08phylib: move to dynamic allocation of struct mii_busLennert Buytenhek
This patch introduces mdiobus_alloc() and mdiobus_free(), and makes all mdio bus drivers use these functions to allocate their struct mii_bus'es dynamically.

2007-10-10[NET] drivers/net: statistics cleanup #1 -- save memory and shrink codeJeff Garzik
We now have struct net_device_stats embedded in struct net_device, and the default ->get_stats() hook does the obvious thing for us. Run through drivers/net/* and remove the driver-local storage of statistics, and driver-local ->get_stats() hook where applicable. This was just the low-hanging fruit in drivers/net; plenty more drivers remain to be updated.

2007-07-18Blackfin ethernet driver: on chip ethernet MAC controller driverBryan Wu
This patch implements the driver necessary use the Analog Devices Blackfin processor's on-chip ethernet MAC controller. [try#2] - add timeout control - kill dma_config_reg bitfields - some trivial cleanup [try#3] - add endianess check - add DRV_NAME, DRV_VERSION... driver information string - add some comments for silicon anomaly and dma API confusion - some code trivial cleanup [try#4] - add Blackfin latest GPIO pin mux opertion with Michael Hennerich's help and Dan's review - rewrite the DMA descriptor list operation in a more readable way by Joe's review [try#5] - cleanup some coding style by Joe's review. [try#6] - 1.1 version fix a bug when set up multicast list pointed by Mr. yoshfuji - rearrange the desc_list_free function.
