Subject: [PATCH iproute2-next v1 3/4] rdma: Add support to get CQ in raw format
Date: Wed, 24 Jun 2020 13:40:11 +0300	[thread overview]
Message-ID: <20200624104012.1450880-4-leon@kernel.org> (raw)
In-Reply-To: <20200624104012.1450880-1-leon@kernel.org>

Add the required support to print CQ data in raw format.

"data":[0,4,255,254,0,0,0,0,0,0,0,0,16,28,...]}]
