| 13:0 | TX_PRI7_MAXLEN | R/W | 7E8h | Transmit Priority 7 Maximum Packet Length. This value determines the maximum packet length that will be transmitted on Ethernet egress for all Ethernet ports. The packet length compared to the maximum length value is the ingress packet length (not the actual egress packet length which is the length before VLAN addition or removal). Packets on a priority that are larger than the CPSW_TX_PRI0_MAXLEN_REG to CPSW_TX_PRI7_MAXLEN_REG value are dropped. The reset value is decimal 2024 when fifo_blk_size=1 and 9604 when fifo_blk_size=4. |
