Subject: [RFC PATCH 04/10] hisilicon: Update drivers to use ethtool_gsprintf
From: Alexander Duyck <alexanderduyck@...com>
Update the hisilicon drivers to make use of ethtool_gsprintf. The general
idea is to reduce code size and overhead by replacing the repeated pattern
of string printf statements and ETH_STRING_LEN counter increments.
Signed-off-by: Alexander Duyck <alexanderduyck@...com>
