The latter is rather intrusive, so I will avoid it. Direct commit to stable/12 since the CI bots are broken. 2021-08-29T10:49:28Z Kyle Evans kevans@FreeBSD.org 2020-10-01T01:10:51Z urn:sha1:befc478229660bca9cbda38d73f6b9d7c8918ded Repeating the default WARNS here makes it slightly more difficult to experiment with default WARNS changes, e.g. if we did something absolutely bananas and introduced a WARNS=7 and wanted to try lifting the default to that. Drop most of them; there is one in the blake2 kernel module, but I suspect it should be dropped -- the default WARNS in the rest of the build doesn't currently apply to kernel modules, and I haven't put too much thought into whether it makes sense to make it so.

Not all kernels have netmap(4) support. Check for netmap(4) support before attempting to run the tests via the `PLAIN_REQUIRE_KERNEL_MODULE(..)` macro. 2. Libraries shouldn't be added to LDFLAGS; they should be added to LIBADD instead. This allows the build system to evaluate dependencies for sanity. 3. Sort some of the Makefile variables per bsd.README. 1., in particular, will resolve failures when running this testcase on kernels lacking netmap(4) support, e.g., the i386 GENERIC kernels on ^/stable/11 and ^/stable/12.

In this cases it is desirable to have more than a pair of RX/TX host rings, and use multiple threads to speed up forwarding. This change adds support for multiple host rings. On registering a netmap port, the user can specify the number of desired receive and transmit host rings in the nr_host_tx_rings and nr_host_rx_rings fields of the nmreq_register structure. 2019-01-10T08:52:50Z Vincenzo Maffione vmaffione@FreeBSD.org 2019-01-10T08:52:50Z urn:sha1:7c72d86998a627e04f55c24e074b45d3d8168213 netmap: unit tests: fix issues found by coverity scan Reported by: asomers Sponsored by: Sunny Valley Networks 2019-01-08T09:40:09Z Vincenzo Maffione vmaffione@FreeBSD.org 2019-01-08T09:40:09Z urn:sha1:1b1076c4254a5134ef59fa3a04b5cf2a1a4c4871 netmap: add suite of unit tests Import the unit tests from upstream (https://github.com/luigirizzo/netmap ba02539859d46d33), and make them ready for use with Kyua.
