[dpdk-dev] Is there any HW requirement for a NIC to use the eventdev API for implementing Rx/Tx?

[Kevin Wilson]

Hi,
According to what I understand from:
http://dpdk.org/doc/guides/eventdevs/index.html

only 3 drivers currently use the eventdev API,
NXP DPAA,NXP DPAA2 and Octeon SSOVF.

My question is: is there any HW requirements from a NIC
so that it will use the eventdev API for RX/TX instead
of the traditional polling mode used by all the other PMD drivers ?
Or theoretically and practically, one can implement DPDK driver using the
eventndev API for Rx/Tx for any NIC ?
