- Match on GTP extension header is not supported in group 0.
+- Flex item:
+
+ - 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 input link - ``eth`` or ``udp``
+ and up to 2 output links - ``ipv4`` or ``ipv6``.
+ - Flex item fields (``next_header``, ``next_protocol``, ``samples``)
+ do not participate in RSS hash functions.
+ - In flex item configuration, ``next_header.field_base`` value
+ must be byte aligned (multiple of 8).
+
- No Tx metadata go to the E-Switch steering domain for the Flow group 0.
The flows within group 0 and set metadata action are rejected by hardware.
