Subject: [dpdk-dev] [PATCH v2 0/4] lpm lookupx4 fixes
Date: Thu, 14 Jan 2021 06:59:21 +0000 [thread overview]
Message-ID: <20210114065926.1200855-1-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20210108082127.1061538-1-ruifeng.wang@arm.com>
This series fixed bug in lpm4 vector lookup implementations.
When more than 256 tbl8 groups are created, lookupx4 could
retrieve next hop data from wrong group.
The bug is there since next_hop field was expanded from
8-bit to 24-bit, and inherited by other implementations.
Also updated test case to improve coverage to detect such
failure.

lpm: fix vector lookup for Arm
lpm: fix vector lookup for x86
lpm: fix vector lookup for ppc64
test/lpm: improve coverage on tbl8
