[Bug 369005] Re: ath5k : disconnection / slow network - "unsupported jumbo" error

[Vince McIntyre]

I'm still seeing occasional "unsupported jumbo" messages, but the card does appear to work fairly reliably,
I have not seen it fall over in days. Thanks Maxim. I haven't made speed tests but it's not irritatingly slow.
Not seeing any "noise floor" messages.
