    sys/pci              if_rl.c 
  Log:
  Locking cleanup for rl(4).
   - Eliminate the use of a recursive mutex.
   - Mark the driver INTR_MPSAFE.
  
  This work is incomplete and will be refined in a future commit.
   - Most notably, _locked() variants of entry points need to be introduced.
   - The mii upcall/downcall may still be racy.
   - Add a stubbed-out guard against racing rl_detach() for the time being.
