Subject: [net-next PATCH v2 2/9] net: dsa: qca8k: convert to GENMASK/FIELD_PREP/FIELD_GET
Date: Mon, 22 Nov 2021 02:03:06 +0100 [thread overview]
Message-ID: <20211122010313.24944-3-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20211122010313.24944-1-ansuelsmth@gmail.com>
Convert and try to standardize bit fields using
GENMASK/FIELD_PREP/FIELD_GET macros. Rework some logic to support the
standard macro and tidy things up. No functional change intended.
