[dpdk-dev] [PATCH 2/2] doc: add description of raw mode in flow director in testpmd

[Kirill Rybalchenko]

Add description of raw flow type mode for flow_director_filter
command in testpmd. Modify description of flow type parameter
for functions set_hash_global_config, set_hash_input_set and
set_fdir_input_set

+* Perfect-raw-flow-type match filters.
+  The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
+  The masked fields are specified by input sets.
+
 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
 per flow type and the flexible payload.
 
 The Flow Director can also mask out parts of all of these fields so that filters
 are only applied to certain fields or parts of the fields.
 
+Note that for raw flow type mode the source and destination fields in the
+raw packet buffer need to be presented in a reversed order with respect
+to the expected received packets.
+For example: IP source and destination addresses or TCP/UDP/SCTP
+source and destination ports
