Subject: [RFC PATCH v2 2/2] net: include: mii: Refactor: Use bit ops for ADVERTISE_* bits
Date: Thu, 6 Jun 2024 10:08:37 +0200
Message-ID: <20240606080836.121056-2-csokas.bence@prolan.hu>

Replace hex values with bit shift and __GENMASK() for readability

Cc: trivial@kernel.org

Signed-off-by: "Csókás, Bence" <csokas.bence@prolan.hu>

Notes:
    Changes since v2:
    * Replace BIT() with bit shift, as the macro is not exported to userspace
    * Use __GENMASK(), exported into userspace in 3c7a8e190bc5
