2009-10-12smsc95xx: fix transmission where ZLP is expectedSteve Glendinning
[ Upstream commit ec4756238239f1a331d9fb95bad8b281dad56855 ] Usbnet framework assumes USB hardware doesn't handle zero length packets, but SMSC LAN95xx requires these to be sent for correct operation. This patch fixes an easily reproducible tx lockup when sending a frame that results in exactly 512 bytes in a USB transmission (e.g. a UDP frame with 458 data bytes, due to IP headers and our USB headers). It adds an extra flag to usbnet for the hardware driver to indicate that it can handle and requires the zero length packets. This patch should not affect other usbnet users, please also consider for -stable. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S.

The smsc95xx driver was forwarding the trailing fcs on received frames up the stack leading to confusion in tcpdump.

2009-05-01smsc95xx: add support for LAN9512 and LAN9514Steve Glendinning
LAN9512 and LAN9514 are USB hubs with an integrated 10/100 ethernet controller. Logically this looks like an ethernet controller (similar to LAN9500) permanently attached to one of the hub's downstream ports. This patch adds the usb device id of the new ethernet controller to the smsc95xx driver. This id is the same in both new devices.

2009-05-01smsc95xx: configure LED outputsSteve Glendinning
SMSC LAN9500 has dual purpose GPIO/LED pins, and by default at power-on these are configured as GPIOs. This means that if LEDs are fitted they won't ever light. This patch sets them to be LED outputs for speed, duplex and link/activity. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-01-25smsc95xx: fix function prototype of async callbackSteve Glendinning
smsc95xx_async_cmd_callback doesn't currently match usb_complete_t, so there's a cast to force the square peg into the round hole. This patch fixes this properly. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-16net: Refactor full duplex flow control resolutionSteve Glendinning
These 4 drivers have identical full duplex flow control resolution functions. This patch changes them all to use one common function. The function in question decides whether a device should enable TX and RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this should also be useful for other drivers.

2008-12-16net: Move flow control definitions to mii.hSteve Glendinning
flags used within drivers for indicating tx and rx flow control are defined in 4 drivers (and probably more), move these constants to mii.h. The 3 SMSC drivers use the same constants (FLOW_CTRL_TX), but TG3 uses TG3_FLOW_CTRL_TX, so this patch also renames the constants within TG3.

2008-11-20smsc95xx: add tx checksum offload supportSteve Glendinning
LAN9500 supports tx checksum offload, which slightly decreases cpu utilisation. The benefit isn't very large because we still require the skb to be linearized, but it does save a few cycles. This patch adds support for it, and enables it by default. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-27net: convert print_mac to %pMJohannes Berg
This converts pretty much everything to print_mac. There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.
