Subject: [PATCH v2] sefltests: net: Add on/off checks for network interface non fixed features

This patch addresses the TODO (add non fixed feature on/off check).
I have tested it manually on my system and made changes as suggested in v1

PATCH v1:
https://lore.kernel.org/all/20240606212714.27472-1-jain.abhinav177@gmail.com/

Changes since v1:
 - Removed the addition of tail command as it was not required after
   below change
 - Used read to parse the temp features file rather than using for loop
   and took out awk/grep/sed from v1
