This issue has been fixed with below change:

        /*
         * Make sure the driver does not transmit packet less than min. as per the
         * Ethernet standards.
         */
        if (totalLen < (uint16)60U)
        {
            uint16 remLenInBytes = ((uint16)60U - totalLen);
            /* Zero pad the packet data to at least 60 known bytes */
            
            (void)memset ( ((void *)(pDataBuffer + totalLen)), 0, 
            (void)memset ( ((void *)(&(pDataBuffer->payload[LenByte]))), 0, 
                      (size_t)remLenInBytes );
            /* With Ethernet FCS, total transmitted size will be the minimum 64 bytes */
            totalLen = (uint16)60U;
        }

May I ask which specific MCAL version is fixing this issue.

Besides, is it convenient to provide me with a document that records the history of Mcal fixing issues?

Regards.
