Subject: [dpdk-dev] [PATCH 06/29] net/ena/base: remove extra properties strings
Date: Fri, 27 Mar 2020 11:18:00 +0100	[thread overview]
Message-ID: <20200327101823.12646-7-mk@semihalf.com> (raw)
In-Reply-To: <20200327101823.12646-1-mk@semihalf.com>

This buffer was never used by the ENA PMD. It could be used for
debugging, but it's presence is redundant now.
