>
> In order to support certain device features, including enabling the PTP
> hardware clock, the ice driver needs to control some registers on the device
> PHY.
>
> These registers are accessed by sending sideband messages. For some
> hardware, these messages must be sent over the device admin queue, while
> other hardware has a dedicated control queue for the sideband messages.
>
> Add the neighbor device message structure for sending a message to the
> neighboring device. Where supported, initialize the sideband control queue
> and handle cleanup.
>
> Add a wrapper function for sending sideband control queue messages that
> read or write a neighboring device register.
>
> Because some devices send sideband messages over the AdminQ, also
> increase the length of the admin queue to allow more messages to be
> queued up. This is important because the sideband messages add additional
> pressure on the AQ usage.
>
> This support will be used in following patches to enable support for
> CONFIG_1588_PTP_CLOCK.
