Subject: [PATCH v2 1/2] include: net: add dsa_cpu_ports function
Date: Tue, 6 Apr 2021 06:50:39 +0200 [thread overview]
Message-ID: <20210406045041.16283-1-ansuelsmth@gmail.com> (raw)
In preparation for the future when dsa will support multi cpu port,
dsa_cpu_ports can be useful for switch that has multiple cpu port to
retrieve the cpu mask for ACL and bridge table.
