Nick Hainke ab7e53e5cc ipq40xx: 5.10: fix ar40xx driver ... This commit is completely based on the work of adron-s: https://github.com/openwrt/openwrt/pull/4721#issuecomment-1101108651 The commit fixes the data corruption on TX packets. Packets are transmitted, but their contents are replaced with zeros. This error is caused by the lack of guard (50 ms) intervals between calibration phases. This error is treated by adding mdelay(50) to the calibration function code. In the original qca-ssda code [0], these mdelays were existing, but in the ar41xx.c they are gone. Tested on: - Fritz!Box 4040 - Fritz!Box 7530 - Mikrotik SXTsq 5AC - ZyXEL NBG6617 - [0] https://git.codelinaro.org/clo/qsdk/oss/lklm/qca-ssdk/-/blob/NHSS.QSDK.11.4/src/init/ssdk_init.c#L2072 Suggested-by: Serhii Serhieiev <adron@mstnt.com> Reviewed-by: Robert Marko <robimarko@gmail.com> Signed-off-by: Nick Hainke <vincent@systemli.org>		2022-04-29 00:27:25 +02:00
