[dts] [PATCH] checksum_offload: Support this test in vector mode

[pvukkisala at marvell.com]

From: Phanendra Vukkisala <pvukkisala at marvell.com>

Send and sniff 4 packets to support vector mode cavium HW stops calculating
check sums upon receiving first incorrect checksum. So accept unknown also as bad
