#include "common/common.h"
T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

L2 table code. This is enough to get the T4's switch + L2 rewrite filters working. (All other filters - switch without L2 info rewrite, steer, and drop - were already fully-functional). Some contrived examples of "switch" filters with L2 rewriting: # cxgbetool t4nex0 iport 0 dport 80 action switch vlan +9 eport 3 Intercept all packets received on physical port 0 with TCP port 80 as destination, insert a vlan tag with VID 9, and send them out of port 3. # cxgbetool t4nex0 sip 192.168.1.1/32 ivlan 5 action switch \ vlan =9 smac aa:bb:cc:dd:ee:ff eport 0 Intercept all packets (received on any port) with source IP address 192.168.1.1 and VLAN id 5, rewrite the VLAN id to 9, rewrite source mac to aa:bb:cc:dd:ee:ff, and send it out of port 0.

- There's no need to overwrite the default device method with the default one. Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily. Discussed with: jhb, marcel - While at it, use DEVMETHOD_END. Discussed with: jhb - Also while at it, use __FBSDID.

- 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?

Many updates to cxgbe(4) - Device configuration via plain text config file. 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

You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place.

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? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place. Everything else, including all "drop" and "pass" rules with RSS or absolute qid, should work. Obtained from: Chelsio Communications

- 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? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

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? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications. MFC after: ~3 months (after 9.1, and after ensuring MFC is feasible)

Do not allocate extra vectors when adapter is not TOE capable (or toecaps have been disallowed by the user). + one very minor unrelated cleanup in t4_sge.c

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?

#ifdef TCP_OFFLOAD
Many updates to cxgbe(4) - Device configuration via plain text config file. 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

- 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?

Fix a couple of bad races that can occur when a cxgbe interface is taken down. The ingress queue lock was unused and has been removed as part of these changes. - An in-flight egress update from the SGE must be handled before the queue that requested it is destroyed. Wait for the update to arrive. - Interrupt handlers must stop processing rx events for a queue before the queue is destroyed. Events that have not yet been processed should be ignored once the queue disappears. MFC after: 1 week

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place.

- 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? Look for toe4 and/or toe6 in the output of netstat and sockstat: # netstat -np tcp | grep toe # sockstat -46c | grep toe Reviewed by: bz, gnn Sponsored by: Chelsio communications.

T4 packet filtering/steering. - Enable 5-tuple and every-packet lookup. - Setup the default filter mode to allow filtering/steering based on IP protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match type; all combined together. You can also filter based on MAC index, Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll have to modify the default filter mode and exclude some of the match-fields in it. IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter rules. - Add driver ioctls to get/set the global filter mode. - Add driver ioctls to program and delete hardware filters. A couple of the "switch" actions that rewrite Ethernet and VLAN information and switch the packet out of another port may not work as the L2 code is not yet in place.

- 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?
