 Teach urndis to handle some REMOTE_NDIS_INDICATE_STATUS_MSG. If the status
 is reasonable, don't tell userland we got an error. Stops spurious EIO.
 From openbsd.
 Fix bug, remove {0,0} because we switched to usb_lookup().
 s/no free/no freelist entry/ in a debug message.
 fix a lock hang reported by sc.dying in PR#54495.
 remove locking in usbnet_tick().  assume that all locking
 needs are handled inside usbnet_tick_task(), which runs in
 the usbtask thread.  ensure that usbnet private is valid
 before using it.
 also check NULL private pointer in usbnet_isdying().
 all the other cases should never happen.
 don't try to set dying when we haven't usbnet_attach()d yet.
 reported by maxv.
 - use CALLARGS vs CALLED for better usbhist
 - turn off usbnetdebug default
 - log for all entry/exit points of usbnet_pipe_intr()
 - in usbnet_start_locked() track whether any packet has been
   transmitted for setting the timer.  avoids spurious
   "watchdog timeouts"
 - in usbnet_stop() use callout_halt() vs callout_halt, and
   also stop the usb task.  fixes crash of usbtask after the
   phy has detached.
 - add a little more defensive checking in the tick task, and
   add some high-log-level logs.
 - in usbnet_detach() move the call to usbnet_stop_ifp() above
   the calls to callout/usbtask stopping.
 - set ec_mii and unp_pri to NULL when freeing their data
 normalise an error message.
 document usbnet_private locking.  minor knf.
