Modified files:
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.
