Subject: Re: [dpdk-dev] [PATCH] lmp: add lookup x4 with x4 default values
Date: Mon, 13 Jan 2020 11:06:31 +0000 [thread overview]
Message-ID: <64889d7e-560b-b7ca-45e1-5a5e3f4c3163@intel.com> (raw)
In-Reply-To: <20200111160827.10021-1-pbhagavatula@marvell.com>
Hi Pavan,
I don't think it is a good idea to add extra function because:
1) it is just a copy of an existing rte_lpm_lookupx4() except the last 4
ternary ops
2) What is a real world use case for that? Usually returned value is
used as an index in an array of next_hop structs.
3) You can have the same result by using special unused defv and
pcmpeqd/vpblendd on a hop[4] after lookup
