Subject: [dpdk-dev] [PATCH v7 15/15] net/enic: use rte_eth_linkstatus_set
Date: Mon, 22 Jan 2018 15:54:58 -0800 [thread overview]
Message-ID: <20180122235458.28562-16-stephen@networkplumber.org> (raw)
In-Reply-To: <20180122235458.28562-1-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).
