Messing with the Realtek nic driver didn't work my pc crashed soon after.


It looks like i've hit on a stable combination at the moment. It's looking 
like either...

* Passing "nomsi" as a kernel parameter has worked somehow, when doing  
/proc/interrupts it looks like everything that used to be using msi is still 
using msi, except possibly the hdmi audio on the video card.

* This patch:

I'm currently running a bit of a frankenstien kernel because I have tried a 
bunch of stuff.

Everything is working at the moment stabily for me, i'm only seeing this when 
doing transfers through the wireless VPN....

[  839.482251] xhci_hcd 0000:02:00.0: WARN Successful completion on short TX: 
needs XHCI_TRUST_TX_LENGTH quirk?
[  844.480798] handle_tx_event: 2158 callbacks suppressed


* I set the TRBS per segment back to 64 and the sg list back to "~0u"

* readq/writeq reversion 

* LPM reversion

* merged usb3-port-power-v4 from 
https://git.kernel.org/cgit/linux/kernel/git/djbw/usb.git/
