Re: Waiting for the PHY to complete auto-negotiation

The problem with this is the following mind-boggling quirk of
the hardware: once RX DMA is enabled, there is no supported
way to disable it! Thus, I'm trying to find a clean way to set
the control flow parameter BEFORE enabling the MAC.

There is no solution. I can pull the cable out, and plug it into a
different computer. The first could use flow control, the second not.

If you cannot disable RX DMA, you should probably disable unloading of
the module. Also kexec.
