I would like to enable it by default in GENERIC to improve test coverage by a general audience and ensure that bugs introduced elsewhere (build bugs, network interface, kernel interface bugs) aren’t ignored by accident when running make tinderbox builds as it’s not built by default.
make tinderbox will build LINT kernels, which for amd64 will include the
As Jason pointed out, all of the IB stack (including the Linux compat
shims) can already be built as a KLD. Why not just make WITH_OFED the
default on amd64 instead? That way the KLDs and userland tools will be
built by default, and the size of the kernel needn't grow.
