Not sure that we can talk about consistency at the moment ... (all the more
so as if you only fixed two pmds).
If we go with this approach, there is still something that won't work.
ixgbe shared code uses DEBUGOUT* macros which are called a lot in this
The macros call sites use trailing \n.
I suppose I will have a big NO from Intel guys if I remove the trailing \n,
so I suppose we can use an alternate macro that calls RTE_LOG rather than
PMD_DRV_LOG in ixgbe_os_dep.h.
I will also remove any reference to DEBUGOUT* in non-shared code.

By the way, did you look at the other patches of this series ?
I want to send a v2 later (maybe not today), so any comment on the other
patches are welcome.
