From 8119e49b68fa1ec778f9ec8be05b5492046100b2 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Sat, 23 Nov 2019 22:30:47 -0500 Subject: bnxt_en: Refactor the initialization of the ethtool link settings. Refactor this logic in bnxt_probe_phy() into a separate function bnxt_init_ethtool_link_settings(). It used to be that the settable link settings will never be changed without going through ethtool. So we only needed to do this once in bnxt_probe_phy(). Now, another function sharing the port may change it and we may need to re-initialize the ethtool settings again in run-time.
