I installed Fedora and the Linux driver must read the value since it picked up 9K: enp19s0: flags=3D4163 mtu 9000 ether 70:70:8b:77:7e:76 txqueuelen 1000 (Ethernet) RX packets 20 bytes 6520 (6.3 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 71 bytes 11070 (10.8 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Going back to CIMC and setting it to 4K, and after a reboot: enp19s0: flags=3D4163 mtu 4000 inet6 fe80::7270:8bff:fe77:7e76 prefixlen 64 scopeid 0x20 ether 70:70:8b:77:7e:76 txqueuelen 1000 (Ethernet) RX packets 14 bytes 4564 (4.4 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 48 bytes 7564 (7.3 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 I was only using FIBs/jails as didn't have a 10Gb switch and/or second serv= er at hand - so I needed two route tables in order to test back-to-back on the same server. So with the interface breaking when changing MTU and the low throughput (<4Gb/s) it might be fair to say the driver is in alpha? I'm happy to test if needed. Testing on Linux for me isn't easy since I kn= ow squat about Linux. --=20 You are receiving this mail because: You are the assignee for the bug.=
