    ice: enable initial devlink support · 1adf7ead
    Jacob Keller authored
    Begin implementing support for the devlink interface with the ice
    driver.
    
    The pf structure is currently memory managed through devres, via
    a devm_alloc. To mimic this behavior, after allocating the devlink
    pointer, use devm_add_action to add a teardown action for releasing the
    devlink memory on exit.
    
    The ice hardware is a multi-function PCIe device. Thus, each physical
    function will get its own devlink instance. This means that each
    function will be treated independently, with its own parameters and
    configuration. This is done because the ice driver loads a separate
    instance for each function.
    
    Due to this, the implementation does not enable devlink to manage
    device-wide resources or configuration, as each physical function will
    be treated independently. This is done for simplicity, as managing
    a devlink instance across multiple driver instances would significantly
    increase the complexity for minimal gain.
