Subject: [net-next PATCH v2 00/10] ethtool: Factor out common code related to
 writing ethtool strings

This patch set is meant to be a cleanup and refactoring of common code bits
from several drivers. Specificlly a number of drivers engage in a pattern
where they will use some variant on an sprintf or memcpy to write a string
into the ethtool string array and then they will increment their pointer by
ETH_GSTRING_LEN.

Instead of having each driver implement this independently I am refactoring
the code so that we have one central function, ethtool_sprintf that does
all this and takes a double pointer to access the data, a formatted string
to print, and the variable arguments that are associated with the string.

Changes from v1:
Fixed usage of char ** vs  unsigned char ** in hisilicon drivers

Changes from RFC:
Renamed ethtool_gsprintf to ethtool_sprintf
Fixed reverse xmas tree issue in patch 2
