[Xenial SRU][PATCH 0/1] UBUNTU: SAUCE: upgrade IXXAT USB SocketCAN driver

[Shrirang Bagul]

BugLink: http://bugs.launchpad.net/bugs/1783241

Several scheduled upgrades to the HMS SocketCAN protocol driver over
USB->CAN interface are required.

SocketCAN support for USB->CAN devices was introduced in Ubuntu Xenial LTS
kernel through following patch (see: http://bugs.launchpad.net/bugs/1774563):
cddf58207a3c UBUNTU: SAUCE: (no-up) Support IXXAT USB SocketCAN device

== SRU Justification ==
The scheduled upgrades include following changes:
- support adapters for CL1 (Communication Layer for legacy devices) and
  CL2 (current devices)
- removed CAN-IDM100 support (Microchip Rev A microcontroller)
- add CAN-IDM101 support (Microchip Rev B microcontroller)
- add Error-Passive recognition
- move CAN message handling to the core module
- use ktime API for timestamps
- fixes Linux kernel coding style issues

== Fix ==
UBUNTU: SAUCE: (no-up) upgrade IXXAT USB SocketCAN driver

== Regression Potential ==
Low. The driver will be built only for amd64 kernels and attach itself to
IXXAT USB-CAN adapters with VID 0x08d8. Also, patches from the vendor (HMS)
have already been tested by Dell/ODM, Canonical QA on Dell 300x Edge IoT
gateways.
