+- Flex item API:
+
+  - Firmware configuration: ``FLEX_PARSER_PROFILE_ENABLE=4 PROG_PARSE_GRAPH=1``.
+  - Hardware support: BlueField-2.
+  - Flex item is supported on PF only.
+  - Hardware limits ``header_length_mask_width`` up to 6 bits.
+  - Firmware supports 8 global sample fields. Each flex item allocates non-shared sample fields from that pool.
+  - Supported flex item can have 1 IN arc - ``eth`` or ``udp`` and up to 2 OUT arcs - ``ipv4`` or ``ipv6``.
+  - Flex item fields (next_header, next_protocol, samples) do not participate in RSS hash functions.
+  - In RTE flex item configuration, ``next_header.field_base`` value must be byte aligned (multiple of 8).
