Thanks a lot for your bug report and the analysis done.
at803x_enable_tx_delay()/at803x_disable_tx_delay() either set BIT 8 of the AT803X_DEBUG_REG_5 register to 1 or 0.
at803x_enable_rx_delay()/at803x_disable_rx_delay() either set BIT 15 of the AT803X_DEBUG_REG_0 register to 1 or 0.
Means, if the call to the disable functions breaks your network connectivity, your system rather needs a call to the enable the bits.
It only worked so far, since the correct values were present on boot and nothing removed (disabled) them till kernel 5.4.
Would you please test if the attached patch fixes your issue.
One or more files have been attached.
