Subject: [dpdk-dev] [PATCH 2/2] test: proceed if timer subsystem was initialized
Date: Fri, 26 Mar 2021 11:47:59 +0100
Message-ID: <20210326104759.280175-3-mk@semihalf.com> (raw)
In-Reply-To: <20210326104759.280175-1-mk@semihalf.com>

From: Stanislaw Kardach <kda@semihalf.com>

rte_timer_subsystem_init() may return -EALREADY if the timer subsystem
was already initialized. This can happen i.e. in PMD code (see
eth_ena_dev_init). This is not an error, rather a notification as the
initialization function simply returns without any action taken.
