Kip Macy 3f345a5d09 Greatly simplify cxgb by removing almost all of the custom mbuf management logic ... - remove mbuf iovec - useful, but adds too much complexity when isolated to the driver - remove driver private caching - insufficient benefit over UMA to justify the added complexity and maintenance overhead - remove separate logic for managing multiple transmit queues, with the new drbr routines the control flow can be made to much more closely resemble legacy drivers - remove dedicated service threads, with per-cpu callouts one can get the same benefit much more simply by registering a callout 1 tick in the future if there are still buffered packets - remove embedded mbuf usage - Jeffr's changes will (I hope) soon be integrated greatly reducing the overhead of using kernel APIs for reference counting clusters - add hysteresis to descriptor coalescing logic - add coalesce threshold sysctls to allow users to decide at run-time between optimizing for forwarding / UDP or optimizing for TCP - add once per second watchdog to effectively close the very rare races occurring from coalescing - incorporate Navdeep's changes to the initialization path required to convert port and adapter locks back to ordinary mutexes (silencing BPF LOR complaints) - enable prefetches in get_packet and tx cleaning Reviewed by: navdeep@ MFC after: 2 weeks		2009-06-19 23:34:32 +00:00
