-Subject: [PATCH] fm10k: add a unit test for FTAG based forwarding
-
-This patch adds a unit test case for FTAG functional test. Before running
-the test, set PORT0_GLORT and PORT1_GLORT environment variables, and ensure
-two fm10k ports are used for dpdk, glort info for each port can be shown in
-TestPoint. In the unit test, a packet will be forwarded to the target port
-by the switch without changing the destination mac address.
