1.According to dpdk commit ddbc8c16a97f ("net/e1000: fix max Rx packet size"): modify shutdown_api/enable_disablejumbo igb pktSize.
2.According to dpdk-26436:If LPE is 1b,the maximum packet size that Foxville can receive is defined in the RLPML.RLPML register.The RLPML.RLPML register was set to MTU + 14 + 4 bytes (must consider at lease 1 VLAN tag since VLAN tag is not included in MTU).
modify tests/mtu_update igb and igc critical values.
