Subject: [PATCH net-next 08/15] bnxt_en: Improve kernel log messages related to ethtool reset.

From: Edwin Peer <edwin.peer@...adcom.com>

Kernel log messages for failed AP reset commands should be suppressed.
These are expected to fail on devices that do not have an AP.  Add
missing driver reload message after AP reset and log it in a common
way without duplication.
