[igt-dev] [PATCH i-g-t 1/3] lib/igt_chamelium: add chamelium_trigger_link_failure

[Simon Ser]

This new function triggers a link failure on the provided port. Another
function called chamelium_supports_trigger_link_failure has been added to
check whether the Chamelium board supports the new method.

Support for TriggerLinkFailure in Chamelium has been added in [1].
