2021-11-02T18:50:51Z

commit 6f7c88691191e6c52ef2543d6f1da8d360b27a24 upstream. Return error code if usb_maxpacket() returns 0 in usbnet_probe() Fixes: 397430b50a36 ("usbnet: sanity check for maxpacket") Reported-by: Hulk Robot Signed-off-by: Wang Hai Reviewed-by: Johan Hovold Link: https://lore.kernel.org/r/20211026124015.3025136-1-wanghai38@huawei.com Signed-off-by: Jakub Kicinski Signed-off-by: Greg Kroah-Hartman

usbnet: sanity check for maxpacket

2021-11-02T18:50:50Z

commit 397430b50a363d8b7bdda00522123f82df6adc5e upstream. maxpacket of 0 makes no sense and oopses as we need to divide by it. Give up.

usbnet: add usbnet_event_names[] for kevent

2021-06-24T19:34:45Z

Modify the netdev_dbg content from int to char * in usbnet_defer_kevent(), this looks more readable. Signed-off-by: Yajun Deng Signed-off-by: David S. Miller

usbnet: run unbind() before unregister_netdev()

2021-06-07T20:23:02Z

unbind() is the proper place to disconnect PHY, but it will fail if netdev is already unregistered. Signed-off-by: Oleksij Rempel Signed-off-by: David S. Miller

usbnet: add method for reporting speed without MII

2021-04-06T23:22:36Z

The old method for reporting link speed assumed a driver uses the generic phy (mii) MDIO read/write functions. CDC devices don't expose the phy. Add a primitive internal version reporting back directly what the CDC notification/status operations recorded. v2: rebased on upstream v3: changed names and made clear which units are used v4: moved hunks to correct patch; rewrote commmit messages Signed-off-by: Oliver Neukum Tested-by: Roland Dreier Reviewed-by: Grant Grundler Tested-by: Grant Grundler Reviewed-by: Andrew Lunn Signed-off-by: David S.

usbnet: add _mii suffix to usbnet_set/get_link_ksettings

2021-04-06T23:22:36Z

The generic functions assumed devices provided an MDIO interface (accessed via older mii code, not phylib). This is true only for genuine ethernet. Devices with a higher level of abstraction or based on different technologies do not have MDIO. To support this case, first rename the existing functions with _mii suffix. v2: rebased on changed upstream v3: changed names to clearly say that this does NOT use phylib v4: moved hunks to correct patch; reworded commmit messages Signed-off-by : Oliver Neukum Tested-by: Roland Dreier Reviewed-by: Grant Grundler Tested-by: Grant Grundler Reviewed-by: Andrew Lunn Signed-off-by: David S.

net: usb: log errors to dmesg/syslog

2021-03-08T19:54:32Z

Errors in protocol should be logged when the driver aborts operations. If the driver can carry on and "humor" the device, then emitting the message as debug output level is fine. Signed-off-by: Grant Grundler Signed-off-by: David S. Miller
