Subject: [PATCH v1 2/4] net/axgbe: add 100 Mbps MAC speed select
Date: Fri, 27 Mar 2026 17:50:04 +0530 [thread overview]
Message-ID: <20260327122011.1534-2-ashokkumar.natarajan@amd.com> (raw)
In-Reply-To: <20260327122011.1534-1-ashokkumar.natarajan@amd.com>
SPEED_100 is not handled, leaving the MAC speed select unprogrammed
when a 100 Mbps link is used.
Add the required speed select (SS) encoding so the MAC is configured
according to the hardware specification for 100 Mbps operation.
Fixes: a5c7273771e8 ("net/axgbe: add phy programming APIs")
