Each virtual interface has its own MAC address, queues, and statistics. The dedicated netmap interfaces (ncxgbeX / ncxlX) were already implemented as additional VIs on each port. This change allows additional non-netmap interfaces to be configured on each port. Additional virtual interfaces use the naming scheme vcxgbeX or vcxlX. Additional VIs are enabled by setting the hw.cxgbe.num_vis tunable to a value greater than 1 before loading the cxgbe(4) or cxl(4) driver. NB: The first VI on each port is the "main" interface (cxgbeX or cxlX). T4/T5 NICs provide a limited number of MAC addresses for each physical port. As a result, a maximum of six VIs can be configured on each port (including the "main" interface and the netmap interface when netmap is enabled). One user-visible result is that when netmap is enabled, packets received or transmitted via the netmap interface are no longer counted in the stats for the "main" interface, but are not accounted to the netmap interface. The netmap interfaces now also have a new-bus device and export various information sysctl nodes via dev.n(cxgbe|cxl).X. The cxgbetool 'clearstats' command clears the stats for all VIs on the specified port along with the port's stats. There is currently no way to clear the stats of an individual VI. 291685: Fix build for !TCP_OFFLOAD case. 291856: Fix RSS build. 297467: Remove #ifdef's from various structures used in the cxgbe/cxl driver. This provides a constant ABI and layout for these structures (especially struct adapter) avoiding some foot shooting. 302110: cxgbe(4): Merge netmap support from the ncxgbe/ncxl interfaces to the vcxgbe/vcxl interfaces and retire the 'n' interfaces. The main cxgbe/cxl interfaces and tunables related to them are not affected by any of this and will continue to operate as usual. The driver used to create an additional 'n' interface for every cxgbe/cxl interface if "device netmap" was in the kernel. The 'n' interface shared the wire with the main interface but was otherwise autonomous (with its own MAC address, etc.). It did not have normal tx/rx but had a specialized netmap-only data path. r291665 added another set of virtual interfaces (the 'v' interfaces) to the driver. These had normal tx/rx but no netmap support. This revision consolidates the features of both the interfaces into the 'v' interface which now has a normal data path, TOE support, and native netmap support. The 'v' interfaces need to be created explicitly with the hw.cxgbe.num_vis tunable. This means "device netmap" will not result in the automatic creation of any virtual interfaces. The following tunables can be used to override the default number of queues allocated for each 'v' interface. nofld* = 0 will disable TOE on the virtual interface and nnm* = 0 to will disable native netmap support. # number of normal NIC queues hw.cxgbe.ntxq_vi hw.cxgbe.nrxq_vi # number of TOE queues hw.cxgbe.nofldtxq_vi hw.cxgbe.nofldrxq_vi # number of netmap queues hw.cxgbe.nnmtxq_vi hw.cxgbe.nnmrxq_vi hw.cxgbe.nnm{t,r}xq{10,1}g tunables have been removed. --- tl;dr version --- The workflow for netmap on cxgbe starting with FreeBSD 11 is: 1) "device netmap" in the kernel config. 2) "hw.cxgbe.num_vis=2" in loader.conf. num_vis > 2 is ok too, you'll end up with multiple autonomous netmap-capable interfaces for every port. 3) "dmesg | grep vcxl | grep netmap" to verify that the interface has netmap queues. 4) Use any of the 'v' interfaces for netmap. pkt-gen -i vcxl... . One major improvement is that the netmap interface has a normal data path as expected. 5) Just ignore the cxl interfaces if you want to use netmap only. No need to bring them up. The vcxl interfaces are completely independent and everything should just work. --------------------- 302263: cxgbe(4): Do not bring up an interface when IFCAP_TOE is enabled on it. The interface's queues are functional after VI_INIT_DONE (which is short of interface-up) and that's all that's needed for t4_tom to communicate with the chip.
