Hi there, I’m working on deploying our new cluster. Masters have 5×1gbps (i210 and i350, thus using igb.ko), configured with mtu 9000, 802.3ad. Works fine *but* I can’t get DCB working (pause frame, aka flow control, which is supported by and enabled on our switches). [root at master2 ~]# dcbtool gc eno1 dcb Command: Get Config Feature: DCB State Port: eno1 Status: Device not capable (I get the same with ELRepo 5.2.15 kmod). Intel datasheet says flow control is available. Can’t find much about it on the web or in kernel git repo. Could someone give me a hand ? Regards, Laurent.
