Subject: [dpdk-dev] [PATCH v5 15/15] net/enic: use rte_eth_linkstatus_set
Date: Tue, 16 Jan 2018 10:37:55 -0800 [thread overview]
Message-ID: <20180116183755.24542-16-stephen@networkplumber.org> (raw)
In-Reply-To: <20180116183755.24542-1-stephen@networkplumber.org>
This driver was not doing atomic update of link status information.
And the return value was different than others.
The hardware also does not do autonegotiation (at least on Linux).
