- Updated TOE support in the kernel. - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded?

- Specialized ingress queues that take interrupts for other ingress queues. Try to have a set of these per port when possible, fall back to sharing a common pool between all ports otherwise. - One control queue per port (used to be one per hardware channel). - t4_eth_rx now handles Ethernet rx only. - sysctls to display pidx/cidx for some queues.

- Move all Ethernet specific items from sge_eq to sge_txq. sge_eq is now a suitable base for all kinds of egress queues. - Add control queues (sge_ctrlq) and allocate one of these per hardware channel. They can be used to program filters and steer traffic (and more). MFC after: 1 week

Initialize various DDP parameters in the main cxgbe(4) driver: - Setup multiple DDP page sizes. When the driver attempts DDP it will try to combine physically contiguous pages into regions of these sizes. - Set the indicate size such that the payload carried in the indicate can be copied in the header mbuf (and the 16K rx buffer can be recycled). - Set DDP threshold to the max payload that the chip will coalesce and deliver to the driver (this is ~16K by default, which is also why the offload rx queue is backed by 16K buffers). If the chip is able to coalesce up to the max it's allowed to, it's a good sign that the peer is transmitting in bulk without any TCP PSH. MFC after: 2 weeks

Also able to operate when not attached to the chip as the master driver. - Generic "work request" queue that serves as the base for both ctrl and ofld tx queues. - Generic interrupt handler routine that can process any event on any kind of ingress queue (via a dispatch table). - A couple of new driver ioctls. cxgbetool can now install a firmware to the card ("loadfw" command) and can read the card's memory ("memdump" and "tcb" commands). - Lots of assorted information within dev.t4nex.X.misc.* This is primarily for debugging and won't show up in sysctl -a. - Code to manage the L2 tables on the chip. - Updates to cxgbe(4) man page to go with the tunables that have changed. - Updates to the shared code in common/ - Updates to the driver-firmware interface (now at fw 1.4.16.0) MFC after: 1 month

Try to have a set of these per port when possible, fall back to sharing a common pool between all ports otherwise. - One control queue per port (used to be one per hardware channel). - t4_eth_rx now handles Ethernet rx only. - sysctls to display pidx/cidx for some queues.
