[RFC,00/10] ethtool: Factor out common code related to writing ethtool strings

Message

Alexander Duyck March 11, 2021, 1:35 a.m. UTC

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_gsprintf that does
all this whch takes a double pointer to access the data, a formatted string
to print, and the variable arguments that are associated with the string.
