I have had a look at the existing rte_log() support in the i40e code in i40e_logs.h and i40e_ethdev.c (line 403 +) and lines 12930 +
The RTE_LIBRTE_I40E_DEBUG_XXX macros are used so this change to config/common_base is needed for dynamic logging too.

The PMD_RX_LOG() seems to only do a printf () which is not what I want.

I would like to keep these two patches which have been acked in the v5 patchset.

I will continue with the dynamic logging after the merge if that is allowed.

Regards,

Bernard
