Subject: [dpdk-stable] [PATCH V3] table: fix bucket empty logic
Date: Wed,  7 Jul 2021 13:19:05 +0200
Message-ID: <ef01a4154319e3ed81389cd082e8acf98b241974.1625656725.git.thierry.herbelot@6wind.com> (raw)
In-Reply-To: <20210524112836.28224-1-thierry.herbelot@6wind.com>

Due to a typo, only 3 out of 4 keys in the bucket of the exact match
table were considered, which can result in valid keys being
incorrectly dropped from the table.

Fixes: d0a00966618ba ("table: add exact match SWX table")
Cc: stable@dpdk.org
