====================
pull-request: can-next 2022-03-10

The first 3 patches are by Oliver Hartkopp, target the CAN ISOTP
protocol and update the CAN frame sending behavior, and increases the
max PDU size to 64 kByte.

The next 2 patches are also by Oliver Hartkopp and update the virtual
VXCAN driver so that CAN frames send into the peer name space show up
as RX'ed CAN frames.

Vincent Mailhol contributes a patch for the etas_es58x driver to fix a
false positive dereference uninitialized variable warning.

2 patches by Ulrich Hecht add r8a779a0 SoC support to the rcar_canfd
driver.

The remaining 21 patches target the gs_usb driver and are by Peter
Fink, Ben Evans, Eric Evenchick and me. This series cleans up the
gs-usb driver, documents some bits of the USB ABI used by the widely
used open source firmware candleLight, adds support for up to 3 CAN
interfaces per USB device, adds CAN-FD support, adds quirks for some
hardware and software workarounds and finally adds support for 2 new
devices.
