[PATCH v2] intel: igb: igb_ethtool.c: Convert kmap() to kmap_local_page()

From: Alaa Mohamed
Date: Fri Apr 15 2022 - 22:02:54 EST


The use of kmap() is being deprecated in favor of kmap_local_page()
where it is feasible.

With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible.
