Installing a centos 9 VM and doing a clang build and comparing the pmdinfo output to the GCC build output, I find there are in fact 3 missing drivers in the output: net_dpaa2, net_ixgbe_vf, and net_sfc_efx. Changing the order of things to move down ixgbe makes ixgbe_vf and sfc_efx reappear, but sadly net_vcpf now disappears. :-( Therefore, more investigation and root causing is needed to find a proper fix. /Bruce
