net: aquantia: Enable coalescing management via ethtool interface
Aquantia NIC allows both TX and RX interrupt throttle rate (ITR)
management, but this was used in a very limited way via predefined
values. This patch allows to setup ITR default values via module
command line arguments and via standard ethtool coalescing settings.
