I think it would be useful if we could pick a device-independent interface for configuring flow control on network interfaces, perhaps as media options via ifconfig. I know that the msk(4) driver allows RX and TX flow control to be toggled via the link0 and link1 flags (the manpage for msk(4) needs updating on this topic I think). I have a hack for work to disable TX flow control on cxgb(4), but it doesn't use flow control currently. Is flow control ethernet- specific? If so, perhaps we could add two new flags for RX and TX flow control to the Ethernet-specific options in that case? Do folks have other ideas? -- John Baldwin
