usbnet: add method for reporting speed without MII

2021-04-06T23:22:36+00:00

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

usbnet: add _mii suffix to usbnet_set/get_link_ksettings

2021-04-06T23:22:36+00:00

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

net: usb: log errors to dmesg/syslog

2021-03-08T19:54:32+00:00

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.

usbnet: switch to core handling of rx/tx byte/packet counters

2020-11-12T22:58:27+00:00

Use netdev->tstats instead of a member of usbnet for storing a pointer
to the per-cpu counters. This allows us to use core functionality for
statistics handling.

Obviously this driver version doesn't make sense. Go with the default
and let ethtool display the kernel version.
