Subject: [dts] [PATCH] checksum_offload: Support this test in vector mode
Date: Wed, 26 Jun 2019 15:43:41 +0530 [thread overview]
Message-ID: <1561544021-9741-1-git-send-email-pvukkisala@marvell.com> (raw)
From: Phanendra Vukkisala <pvukkisala@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
