Hi,=20 We are losing information here. Even if the configuration options should no= t be documented based on an explicit reference make and config_base assumpt= ions (agreed that they are no longer there), the steps should still capture= the conf to be passed to meson so that the PMD can still be built with the= avx2/avx512 intel libraries (ie. not the case by default due to additional= dependency to retrieve the related libraries).=20 Thanks Nic
