Subject: [PATCH net-next 4/7] net: xilinx: axienet: Add 10G/25G (XXV) ethernet support
Date: Thu, 23 Jul 2026 18:08:35 +0530 [thread overview]
Message-ID: <20260723123838.125145-5-suraj.gupta2@amd.com> (raw)
In-Reply-To: <20260723123838.125145-1-suraj.gupta2@amd.com>
The AXI Ethernet driver currently supports only the AXI 1G Ethernet IP.
Add support for the Xilinx XXV Ethernet IP[1], which implements a 10G/25G
Ethernet MAC with PCS/PMA driving a high-speed serial transceiver, as
specified by the 25G Ethernet Consortium.
Add the XXV-specific logic in new xilinx_axienet_xxv.c/.h files and
describe the MAC through an axienet_10g25g_config that provides the
capability flags and callbacks (GT reset, link-ready polling, options
programming, phylink caps, PCS ops, register dump and probe-time init).
No MAC-specific conditionals are added to the shared paths.
Also propagate the axienet_device_reset() failure in axienet_open(),
which was previously overwritten by phylink_of_phy_connect() before being
checked. This matters for XXV, whose mac_init() can fail on a GT
reset-done timeout.
