2009-09-22smsc95xx: fix transmission where ZLP is expectedSteve Glendinning
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. Miller <davem@davemloft.net>

2009-08-14usbnet: add rx queue pausingJussi Kivilinna
Add rx queue pausing to usbnet. This is needed by rndis_wlan so that it can control rx queue and prevent received packets from being send forward before rndis_wlan receives and handles 'media connect'-indication. Without this establishing WPA connections is hard and fail often.

2009-08-04usbnet: allow "minidriver" to prevent urb unlinking on usbnet_stopJussi Kivilinna
rndis_wlan devices freeze after running usbnet_stop several times. It appears that firmware freezes in state where it does not respond to any RNDIS commands and device have to be physically unplugged/replugged. This patch lets minidrivers to disable unlink_urbs on usbnet_stop through new info flag.

2009-03-01usbnet: make usbnet_get_link() fall back to ethtool_op_get_link()Bjørn Mork
Make usbnet_get_link() fall back to ethtool_op_get_link() instead of defaulting to 1. This makes usbnet_get_link return valid results without the need for a driver specific check_connect or mii ops as long as the driver calls netif_carrier_{on,off}() as appropriate. cdc_ether is an example of such a driver.

2007-05-09Move USB network drivers to drivers/net/usb.Jeff Garzik
It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.
