From: "Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>
Date: Tue, 26 Oct 2021 11:06:01 +0100
Subject: [PATCH 1/3] net: phy: add phy_interface_t bitmap support
Add support for a bitmap for phy interface modes, which includes:
- a macro to declare the interface bitmap
- an inline helper to zero the interface bitmap
- an inline helper to detect an empty interface bitmap
- inline helpers to do a bitwise AND and OR operations on two interface
bitmaps
