 - Multi arch support: x86_64 and POWER8.
-- RSS, also known as RCA, is supported. In this mode the number of
-  configured RX queues must be a power of two.
-- VLAN filtering is supported.
 - Link state information is provided.
-- Promiscuous mode is supported.
-- All multicast mode is supported.
-- Multiple MAC addresses (unicast, multicast) can be configured.
-- Scattered packets are supported for TX and RX.
-- Inner L3/L4 (IP, TCP and UDP) TX/RX checksum offloading and validation.
-- Outer L3 (IP) TX/RX checksum offloading and validation for VXLAN frames.
-- Secondary process TX is supported.
 - RX interrupts.
 
-Limitations
------------
-
-- RSS hash key cannot be modified.
-- RSS RETA cannot be configured
-- RSS always includes L3 (IPv4/IPv6) and L4 (UDP/TCP). They cannot be
-  dissociated.
-- Hardware counters are not implemented (they are software counters).
