Subject: [PATCH] net/vmxnet3: keep link state consistent

[ upstream commit 3a14b29bff9cc427920c83391b37cededa48fd2f ]

The vmxnet3 never attempts link speed negotiation.  As a virtual device
the link speed is vague at best.  However, it is important for certain
applications, like bonding, to see a consistent link_status.  802.3ad
requires that only links of the same cost (link speed) be enslaved.
Keeping the link status consistent in vmxnet3 avoids races with bonding
enslavement.

Fixes: 1e3a958f40b3 ("ethdev: fix link autonegotiation value")
