cdc_ether: Ignore bogus union descriptor for RNDIS devices

2012-05-06T17:11:55+00:00

Some RNDIS devices include a bogus CDC Union descriptor pointing
to non-existing interfaces.  The RNDIS code is already prepared
to handle devices without a CDC Union descriptor by hardwiring
the driver to use interfaces 0 and 1, which is correct for the
devices with the bogus descriptor as well. So we can reuse the
existing workaround.

usbnet: fix failure handling in usbnet_probe

2012-05-03T00:13:04+00:00

If register_netdev returns failure, the dev->interrupt and
its transfer buffer should be released, so just fix it.

usbnet: fix leak of transfer buffer of dev->interrupt

2012-05-03T00:13:03+00:00

The transfer buffer of dev->interrupt is allocated in .probe path,
but not freed in .disconnet path, so mark the interrupt URB as
URB_FREE_BUFFER to free the buffer when the URB is destroyed.

smsc75xx: enable mac to detect speed/duplex from phy

2012-05-01T01:52:42+00:00

This patch sets the automatic speed and duplex detection bits
in MAC_CR to enable the mac to determine its speed automatically
from the phy.

Note this must be done BEFORE the receiver or transmitter is
enabled.

smsc75xx: fix phy interrupt acknowledge

2012-05-01T01:52:41+00:00

smsc75xx phy interrupt acknowledge needs an mdio_write to clear
PHY_INT_SRC instead of just a read like in smsc95xx.

smsc75xx: fix mdio reads and writes

2012-05-01T01:52:40+00:00

smsc75xx needs MII_ACCESS_BUSY to be set to correctly trigger mdio I/O.  Note smsc75xx is different from smsc95xx in this regard.

smsc75xx: mark link down on startup and let PHY interrupt deal with carrier changes

2012-05-01T01:52:39+00:00

This patch fixes the same issue as reported on smsc95xx, where the
usb device is connected with no ethernet cable plugged-in.

Without this patch sysfs reports the cable as present

flag@flag-desktop:~$ cat /sys/class/net/eth0/carrier
1

while it's not:

flag@flag-desktop:~$ sudo mii-tool eth0
eth0: no link
