Thanks John! - Tweaked watchdog handling to avoid any false positives, now detection is in the TX clean path, with only the final check and init happening in the local timer. - limit queues to 8 for all devices, with 82576 or 82580 on larger machines it can get greater than this, and it seems mostly a resource waste to do so. Even 8 might be high but it can be manually reduced. - use 2k, 4k and now 9k clusters based on the MTU size. - rework the igb_refresh_mbuf() code, its important to make sure the descriptor is rewritten even when reusing mbufs since writeback clobbers things.
