There are currently 3 in-flight series that adds glues to DW XPCS and stmmac: This one, The Rockchip one from Coia [1] The S32 one from Jan [2] [1] : https://lore.kernel.org/netdev/20260922200336.2201212-1-coiaprant@gmail.com/ [2] : https://lore.kernel.org/netdev/20260919-s32g_serdes-v3-0-9d68868c1e89@oss.nxp.com/ MAINTAINERS entry for XPCS says : SYNOPSYS DESIGNWARE ETHERNET XPCS DRIVER L: netdev@vger.kernel.org S: Orphan F: drivers/net/pcs/pcs-xpcs.c F: drivers/net/pcs/pcs-xpcs.h F: include/linux/pcs/pcs-xpcs.h It would nice if some of you could help maintain the core XPCS driver, and make sure these series aren't stepping on one another :( I personnaly don't have any XPCS HW for tests. You don't have to do it alone, multiple people can co-maintain that :) Maybe Synopsys folks can also chime in ? Maxime
