June 2026 summary: Implemented a critical compatibility fix in DragonBluep/openwrt that enables CPU/SerDes port probing on firmware versions older than 1.0.84 by ungating ports 9 and 13 in the MxL862xx DSA switch driver. This allows legacy devices (e.g., BananaPi BPi-R4 Pro 8X) to probe ports and perform firmware updates, addressing a regression observed with older firmware (e.g., 1.0.70). The change was committed as 5575e4a97f119f682223a090c4a78c0913f906f5 and backported across kernel versions 6.12 and 6.18 to maintain parity. On-device testing validated probing on 1.0.70 with kernel 6.18; ports 9 and 13 are now functional while others remain gated. Impact: improved accessibility and upgradeability of legacy devices, reduced field service and customer support costs, and extended device lifecycles. Technologies used: Linux kernel driver work (MxL862xx DSA switch driver), phylink_caps handling, backporting to multiple kernel versions, and hardware testing on BananaPi platforms.
