Add trunking support to the driver. Trunking is found on more recent asics. In general, trunking appears as a single "port" to the driver and overall behavior doesn't differ. Link speed is reported as an aggregate value, while link speed control is done on a per-physical link basis with all links in the trunk symmetrical. Some commands returning port information are updated to additionally provide trunking information. And new ACQEs are generated to report physical link events relative to the trunk. This patch contains the following modifications: Added link speed settings of 128GB and 256GB. Added handling of trunk-related ACQEs, mainly logging and trapping of physical link statuses. Added additional bsg interface to query trunk state by applications.
