[dpdk-dev] [PATCH v6 14/14] net/enic: use ethdev linkstatus helper functions

[Ferruh Yigit]

From: Stephen Hemminger <stephen at 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).
