mgondium:

Unstable wan interface link on tplink 841nd/v9 running trunk/ath79. This goes all the way back to the ath79 migration, on both 4.19 and 5.4 kernels. Other hardware versions have similar problems with link instability, not sure if related since for them the problem is on the lan switch (MII vs GMII ?).
The only current remedy is to go back to ar7x/9x.
