Dear Ethernet experts,
ST prepares a fix for RX descriptors initialization issue reported here previously.
Please can you take a look?

Ah thanks for the suggestion to check the watchdog timers.
Our tcp accept has an issue during initialization. It is reaching a debug assert -> debug print (blocks) -> watchdog timer initiates reset.
So we had (RxDesc + (ETH_RX_DESC_CNT)) delaying long enough to hide the bug and (RxDesc + (ETH_RX_DESC_CNT - 1)) is correct.
Apologies for the extra noise.
