 Committed By:	skrll

 Modified Files:

 Log Message:
 Recover from channel halt errors by using the 3 strikes xacterr rule.

 Adapted from the RaspberryPI linux driver.

 This allows the rum(4) I was sent to be somewhat usable. Need to
 investigate further what is causing the problem in the first place.

 Might help PR/49019 (RPI: interrupt storm when url0 is up)

 I found that same problem occurs when I connect uplcom
 (Prolific ucom) to RPI and do "cu -l ttyU0".
 usbdevs -dv reports it's full speed device.

 Thanks for taking care of this problem.

 The USB interrupt rate is now ~10000 when
 devices are up or opened.
 ucom, kue, and udav(UDAV_NO_PHY) work fine.
 url cannot detect carrier (ifconfig show 'no carrier')
 and link LED blinks periodically (about 6.5 sec).

 Good news.

 I guess url needs

   urlphy* at mii? phy ?                 # Realtek RTL8150L internal PHYs

 Perhaps all of your ethernet usb devices could do with other PHYs adding 
 to the RPI config file?

 Bingo! My RPI kernel and generic kernel for RPI lack urlphy.
 url(4) now works fine by adding urlphy to the config file.
 Thank you.
