[PATCH 4.14 52/71] nfp: use the correct index for link speed table

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 0d9c9f0f40ca262b67fc06a702b85f3976f5e1a1 ]

sts variable is holding link speed as well as state.  We should
be using ls to index into ls_to_ethtool.

Fixes: 265aeb511bd5 ("nfp: add support for .get_link_ksettings()")
