AMD TCPDirect ultra low latency kernel bypass TCP and UDP implementation for AMD Solarflare network adapters, to be used with corresponding versions of Onload®️ at https://github.com/Xilinx-CNS/onload. The stable branch is currently `v8_1`.
On older distros __DECLARE_FLEX_ARRAY macro is not defined and so builds fail. Fix this by including the definition from zf_emu.h into zf_emu_superbuf.h
Testing done
Jenkins
Jenkins pipeline passes (don't know if I can post links here or not), but some tests are a bit flaky.
Manual
Also ran unit tests on my DUT with make test. There were some failures, but the same tests failed with old versions of onload+zf without my recent fixes, so I don't think it is a regression (potentially just a setup issue).
New versions:
