History
Richard Hughes b333e0045c Split out a shared system context 
There is a lot of code in fwupd that just assigns a shared object type to
a FuPlugin, and then for each device on that plugin assigns that same shared
object to each FuDevice.

Rather than proxy several kinds of information stores over two different levels
of abstraction create a 'context' which contains the shared *system* state
between the daemon, the plugins and the daemon.

This will allow us to hold other per-machine state in the future, for instance
the system battery level or AC state.

BCM57xx Support

Introduction

This plugin updates BCM57xx wired network adaptors from Broadcom using a reverse-engineered flashing protocol. It is designed to be used with the clean-room reimplementation of the BCM5719 firmware found here: https://github.com/meklort/bcm5719-fw

Protocol

BCM57xx devices support a custom com.broadcom.bcm57xx protocol which is implemented as ioctls like ethtool does.

GUID Generation

These devices use the standard PCI instance IDs, for example:

  • PCI\VEN_14E4&DEV_1657
  • PCI\VEN_14E4&DEV_1657&SUBSYS_17AA222E

Update Behavior

The device usually presents in runtime mode, and the firmware is written to the device without disconnecting the working kernel driver. Once complete the APE is reset which may cause a brief link reconnection.

On flash failure the device is nonfunctional, but is recoverable using direct BAR writes, which is typically much slower than updating the device using the kernel driver and the ethtool API.

Vendor ID Security

The vendor ID is set from the PCI vendor, in this instance set to PCI:0x14E4

External interface access

This plugin requires the SIOCETHTOOL ioctl interface.
