Known issues

See reporting bugs if you encounter issues with this release.

Broken MV88E6176 switch

Devices featuring the MV88E6176 integrated switch are currently broken in 22.03: the switch behaves as a hub, meaning network packets will be sent to all ports. This bug is documented in (FS#11077). This problem is only seen with kernel 5.10. OpenWrt 21.02 and OpenWrt master are not affected.
