I350-T2v2 2.2.6-RELEASE Trying to Disable Flow Control
-
I have been trying to disable flow control for the i350-T2, but have been unable. The instructions have been followed, but it seems that particular settings are ignored. I have used:
hw.igb.fc_setting=0
dev.igb.0.fc=0
dev.igb.1.fc=0I have tried in boot/loader.conf boot/loader.conf.local and even etc/sysctrl.conf. None of the settings used nor the locations used will disable flow control. sysctrl dev.igb will always reports dev.igb.0.fc: 3 and dev.igb.1.fc: 3
Seemingly something simple ends up being a bit complicated. Any insight and help to this is much appreciated.

Add it under System>Advanced, Tunables tab.

Thank you, that was one area in which I didn't think of using. The reason as to why, is that the tunable, kern.ipc.nmbclusters=131072, did not work when configured this way. At first tunable hw.igb.fc_setting=0 didn't work, but I am persistent and there are a few possible configurations. So, I used dev.igb.0.fc=0 and dev.igb.1.fc=0 as tunables and finally flow control was disabled on WAN and LAN. I also configured hw.igb.header_split: 1 but that didn't work as a tunable. However, flow control is finally disabled, and that was my goal.
Thank you
