+Subject: [PATCH] app/testpmd: fix key for RSS flow rule
+
+Since the patch '1848b117' has initialized the variable 'key' in
+'struct rte_flow_action_rss' with 'NULL', the PMD cannot get the
+RSS key now. Details as bellow:
+
+testpmd> flow create 0 ingress pattern eth / ipv4 / end actions
+         rss types ipv4-other end key
+         1234567890123456789012345678901234567890FFFFFFFFFFFF123
+         4567890123456789012345678901234567890FFFFFFFFFFFF
+         queues end / end
+Flow rule #1 created
+testpmd> show port 0 rss-hash key
+RSS functions:
+         all ipv4-other ip
+RSS key:
+         4439796BB54C5023B675EA5B124F9F30B8A2C03DDFDC4D02A08C9B3
+         34AF64A4C05C6FA343958D8557D99583AE138C92E81150366
+
+This patch sets offset and size of the 'key' variable as the first
+parameter of the token 'key'. Later, the address of the RSS key will
+be copied to 'key' variable.
+
