Add a mention about the kernel requirement here too please.

Missing newline.

I understood that IOVA as VA is possible with kernel >= 4.6.
Should it be < ?

You removed this part, but we don't have to consider kni things if
RTE_LIBRTE_KNI is not compiled in.

The check on physical address availability has been lost.

You are forcing this even if the user specified a iova mode.


In the end, can't we just change the check on the workaround?
Something like:

@@ -1085,7 +1085,7 @@ rte_eal_init(int argc, char **argv)
                                RTE_LOG(DEBUG, EAL, "IOMMU is not

                                rte_eal_check_module("rte_kni") == 1) {


It would be the only change in the whole file lib/librte_eal/linux/eal/eal.c

Should this check still apply with kernel < 4.6?
