Subject: [PATCH v2 net-next 3/7] net: dsa: sja1105: Add static config tables for scheduling
Date: Sat, 14 Sep 2019 04:17:58 +0300 [thread overview]
Message-ID: <20190914011802.1602-4-olteanv@gmail.com> (raw)
In-Reply-To: <20190914011802.1602-1-olteanv@gmail.com>
In order to support tc-taprio offload, the TTEthernet egress scheduling
core registers must be made visible through the static interface.
