The driver exists two issues: 1. For RX buffer, current driver release the buffer too early, should wait until free_pkt callback is called. Otherwise, the released buffer will put into rx bd ring again and may be used by enetc when uboot is processing the packet. 2. The RX BD size is only 16 bytes, but cache line is 64 bytes on iMX95, so when flush a free RX BD to submit it ring, the flush may write adjacent BDs which locate in same cache line into memory. It has the possibility that netc has used (filled) this adjacent BD before uboot processes it. So the BD content is overwritten. It will cause polling Ready bit of this BD always failed. We already observed such issue in 1000Mbps network. The patch added the free_pkt call back implementation for issue #1. And for issue #2, it adjusts to submit BDs in cache line size to ring. For example, on iMX95, we submit 4 RX BDs which are in one cache line. The cache operations are also re-fined in the patch with clean codes.
