Frames with byte counts greater than the value in CPSW_P0_RX_MAXLEN_REG are long frames. Long frames with no errors are oversized frames. Long frames with CRC, code, or alignment error are jabber frames. The maximum value is 9604 (including VLAN) when fifo_blk_size = 4. When fifo_blk_size = 1 the maximum value is 2024 (including VLAN). |
