Hi,
Please backport commit f9317ae5523f99999fb54c513ebabbb2bc887ddf ("net:
lantiq: Add locking for TX DMA channel") to kernel 5.4.
https://git.kernel.org/linus/f9317ae5523f99999fb54c513ebabbb2bc887ddf
The fix commit was added upstream with kernel 5.9 and fixes a problem
introduced in commit fe1a56420cf2 ("net: lantiq: Add Lantiq / Intel
VRX200 Ethernet driver") with kernel 4.20.
Multiple users reported in the ticket to integrate this into OpenWrt
that this fixes TX hangs for them.
