Hi Danish,
some feedback from my side.

This function appears to be unused. Perhaps it would be better placed in a later patch?
Or perhaps not, if it makes it hard to split up the patches nicely. In which case, perhaps the __maybe_unused annotation could be added, temporarily.
Flagged by clang-16 W=1, and gcc=12 W=1 builds. Likewise for other issues flagged below regarding function declarations/definitions.

This function is only used in this file. Please consider making it static.

This function also appears to be unused.

This function also appears to be unused.

This function is also only used in this file.

icssg_class_set_host_mac_addr() is defined in icssg_classifier.c but used here in icssg_config.c.
Please consider providing a declaration of this function, ideally in a .h file.

This function also appears to be unused.

Ditto.
