The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=351fad05e075c388dece4cd6dd8613494b870bad commit 351fad05e075c388dece4cd6dd8613494b870bad Author: Brian Scott <bscott@bunyatech.com.au> AuthorDate: 2026-05-11 16:54:04 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2026-05-12 14:00:10 +0000 if_eqos_starfive: Read MAC address from device tree u-boot/opensbi determines the ethernet MAC address from ROM and passes it to the OS in the device tree. This change sets the correct MAC address from this source. This prevents the eqos class driver from generating random MAC addresses at each boot. Tested on Starfive VisionFive 2, riscv64 SBC.
