You're right. Its broken since the commit	"ETH_MQ_RX_NONE should disable RSS":
http://dpdk.org/browse/dpdk/commit/?id=243db2ddee3094a2cb39fdd4b17e26df4e7735e1

RSS can be configured or disabled with testpmd options or commands.
So it must be fixed in 2 places:
- in app/test-pmd/parameters.c for options
- in app/test-pmd/cmdline.c for commands
When setting rss_hf, mq_mode must be set accordingly.

Note that DCB feature can use mq_mode.

Thanks for the report. Patch is welcome :)
