smsc95xx: fix transmission where ZLP is expected

2009-09-22T21:28:26+00:00

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.

usbnet: add rx queue pausing

2009-08-14T13:14:04+00:00

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.

[v2] - removed unneeded use of skb_clone

rndis_host: allow rndis_wlan to see all indications

2009-08-04T20:44:17+00:00

Allow rndis_wlan to see all indications. Currently rndis_host lets rndis_wlan to
know about link state changes only, but there is whole set of other
802.11-specific indications that rndis_wlan should handle properly. So rename
link_change() to indication() and convert rndis_wlan to use it.

usbnet: allow "minidriver" to prevent urb unlinking on usbnet_stop

2009-08-04T20:44:15+00:00

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.

usbnet: Add stop function pointer to 'struct rndis_data'.

2009-07-10T18:57:52+00:00

Allow minidriver to know that netdev has stopped. This is to let
wireless turn off radio when usbnet dev is stopped.

usbnet: allow type check of devdbg arguments in non-debug build

2009-01-21T20:35:43+00:00

Improve usbnet's devdbg to always type-check diagnostic arguments,
like dev_dbg (device.h).  This makes no change to the resulting size of
usbnet modules.

This patch also removes an #ifdef DEBUG directive from rndis_wlan so
it's devdbg statements are always type-checked at compile time.
