I could come up with these strategies: - if swconfig is still working in v5.10 with reasonable efforts, the easy way out could be to stick with swconfig for the TESTING_KERNEL introduction - and switch over to DSA as soon as it is acceptable to get rid of kernel v5.4. - adding kernel version based conditionals to - target/linux/ipq806x/base-files/etc/board.d/02_network - target/linux/ipq806x/base-files/etc/board.d/05_compat-version (new) - target/linux/ipq806x/image/Makefile (checking for TESTING_KERNEL) and toggling DEVICE_COMPAT_VERSION between them as needed. This does require (and enforces via DEVICE_COMPAT_VERSION) nuking the existing configuration between v5.4 and v5.10 based builds, but would allow building either from the same source. - if DSA is mostly working on kernel v5.4 (or could be retrofitted *easily*), switching kernel v5.4 in master over to DSA might be another option. "the dsa driver still lacks vlan support in kernel 5.4" suggests that this wouldn't be a reasonable option though. Just two questions of my own. I think to remember that introducing DSA based drivers is slightly at odds with devices storing the MAC address in ASCII representation (uboot-env) rather than binary at a fixed offset, is that an issue here? This affects linksys,ea7500-v1, linksys,ea8500 and zyxel,nbg6817 Is setting tx-fifo-depth still necessary/ useful? http://lists.infradead.org/pipermail/openwrt-devel/2020-September/031417.html Regards Stefan Lippers-Hollmann _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
