How do you imagine memory tagging?
Should it be a parameter when requesting some memory from rte_malloc
or rte_mempool?
Could it be a bit-field allowing to combine some properties?
Does it make sense to have "DMA" as one of the purpose?
How to transparently allocate the best memory for the NIC?
You take care of the NUMA socket property, but there can be more
requirements, like getting memory from the NIC itself.
+Cc more people (6WIND, Cavium, Chelsio, Mellanox, Netronome, NXP, Solarflare)
in order to trigger a discussion about the ideal requirements.
