From 9a82633c27cdfbc33e34876dff41abdbfa71bb97 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Thu, 9 Nov 2017 11:46:28 -0600 Subject: [PATCH] net/bnxt: fix link handling and configuration Remove a case where we were sending a deprecated field to the FW. There is no need to send auto_link_speed to the FW. Also set the auto_mode correctly depending on the setting requested.
