Subject: [PATCH net-next 3/5] selftest: include dst-ip in ethtool ntuple rules

From: Edward Cree <ecree.xilinx@...il.com>

sfc hardware does not support filters with only ipproto + dst-port;
 adding dst-ip to the flow spec allows the rss_ctx test to be run on
 these devices.

Signed-off-by: Edward Cree <ecree.xilinx@...il.com>

I'm not sure if this change will break the test for other drivers that
perhaps support the old filter but not the new one.  If so we might
need to add an option to cfg to control this choice.
