Product: Networking Version: 2.5 Kernel Version: 4.10.1 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other Assignee: step...@networkplumber.org Reporter: daz...@gmail.com Regression: No Bond0 interface doesn't accept MTU higher than 1500.I can set MTU perfectly fine for the slave devices. Recreating the bond0 didn't help to up the MTU. 05:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) 05:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) [ 1626.840818] bond0: Invalid MTU 9000 requested, hw max 1500 [ 1668.913497] ixgbe 0000:05:00.0 enp5s0f0: changing MTU from 1500 to 9000 [ 1669.176015] ixgbe 0000:05:00.0 enp5s0f0: speed changed to 0 for port enp5s0f0 [ 1669.237523] ixgbe 0000:05:00.0 enp5s0f0: detected SFP+: 5 [ 1669.487920] ixgbe 0000:05:00.0 enp5s0f0: NIC Link is Up 10 Gbps, Flow Control: RX/TX [ 1675.591234] ixgbe 0000:05:00.1 enp5s0f1: changing MTU from 1500 to 9000 [ 1675.855232] ixgbe 0000:05:00.1 enp5s0f1: speed changed to 0 for port enp5s0f1 [ 1675.911259] ixgbe 0000:05:00.1 enp5s0f1: detected SFP+: 6 [ 1676.159087] ixgbe 0000:05:00.1 enp5s0f1: NIC Link is Up 10 Gbps, Flow Control: RX/TX [ 1684.745389] bond0: Invalid MTU 9000 requested, hw max 1500 Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer3+4 (1) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: slow Min links: 0 Aggregator selection policy (ad_select): stable System priority: 65535 System MAC address: 90:e2:ba:15:68:20 Active Aggregator Info: Aggregator ID: 2 Number of ports: 2 Actor Key: 13 Partner Key: 221 Partner Mac Address: 02:1c:73:b2:9a:29 Slave Interface: enp5s0f0 MII Status: up Speed: 10000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:15:68:20 Slave queue ID: 0 Aggregator ID: 2 Actor Churn State: none Partner Churn State: none Actor Churned Count: 0 Partner Churned Count: 0 details actor lacp pdu: system priority: 65535 system mac address: 90:e2:ba:15:68:20 port key: 13 port priority: 255 port number: 1 port state: 61 details partner lacp pdu: system priority: 32768 system mac address: 02:1c:73:b2:9a:29 oper key: 221 port priority: 16000 port number: 373 port state: 61 Slave Interface: enp5s0f1 MII Status: up Speed: 10000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:15:68:21 Slave queue ID: 0 Aggregator ID: 2 Actor Churn State: none Partner Churn State: none Actor Churned Count: 0 Partner Churned Count: 0 details actor lacp pdu: system priority: 65535 system mac address: 90:e2:ba:15:68:20 port key: 13 port priority: 255 port number: 2 port state: 61 details partner lacp pdu: system priority: 32768 system mac address: 02:1c:73:b2:9a:29 oper key: 221 port priority: 17000 port number: 33141 port state: 61 Settings for enp5s0f0: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full 10000baseT/Full Supported pause frame use: Symmetric Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full 10000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Speed: 10000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: external Auto-negotiation: on Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes Settings for enp5s0f1: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full 10000baseT/Full Supported pause frame use: Symmetric Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full 10000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Speed: 10000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: external Auto-negotiation: on Supports Wake-on: d Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: yes -- You are receiving this mail because: You are the assignee for the bug.
