Subject: ice: Refactor promiscuous functions
Patch-mainline: v5.17-rc1
Git-commit: fabf480bf95d71c9cfe8a8d6307e0035df963a6a
References: jsc#PED-376
Some of the promiscuous mode functions take a boolean to indicate
set/clear, which affects readability. Refactor and provide an
interface for the promiscuous mode code with explicit set and clear
promiscuous mode operations.
