["matthew green" <mrg%netbsd.org@localhost>]

Module Name:    src
Committed By:   mrg
Date:           Fri Aug 23 04:29:28 UTC 2019

Modified Files:
        src/sys/dev/usb: usbnet.c

Log Message:
- remove unused uncd_rx_cnt
- add USBNETHIST_CALLARGSN and use it in many places
- add more history logs
- add a log if watchdog abort leaves uncd_tx_cnt non zero
- add a unique (32-bit) number for a each usbnet device and
  use it for logging
- explicitly check for full tx ring in usbnet_start_locked()
  and return early, which avoids setting the 5 second timer
  and triggering a watchdog
- reset uncd_tx_prod and uncd_tx_cnt to zero in stop
