From 27df96b2846f6592b0efd7b374f5ac3af3c9276d Mon Sep 17 00:00:00 2001 From: Leyi Rong Date: Wed, 19 Jun 2019 23:18:07 +0800 Subject: [PATCH] net/ice/base: disable Tx pacing option With the current NVM, after GLOBR, before the first link up event, FW will return to base driver, the pacing value of 20 percents for some reason, in the get-link-status AQ command. We then use this value as the pacing param for the set-mac-info AQ command. As result, we are limited to 20 percents of the available bandwidth until the first set-mac-info AQ call after the link up event.
