The latter is the preferred way to copy ethtool strings.
Avoids manually incrementing the pointer. Cleans up the code quite well.

v2: add iwl-next tag. use inline int in for loops.

for ice, igb, igc, and ixgbe the current code already uses ethtool
string helpers, and in many places you are just changing variable name,
"p" to "data", I would rather avoid that.
sorry for not spotting that earlier, and apologies that we have so many
drivers to fix up in the first place
