Module Name:    src
Committed By:   ozaki-r
Date:           Tue Jul  1 10:35:18 UTC 2014

Modified Files:
        src/sys/dev/pci: if_wm.c

Log Message:
Make if_wm MPSAFE

- Make it MPSAFE only when NET_MPSAFE
  - otherwise, its instructions are almost same as before
  - the only change is IFQ_POLL/IFQ_DEQUEUE which
    is now single IFQ_DEQUEUE
- Protect driver operations with a lock
  - further work would make it separate
- Apply MPSAFE flag to
  - callout_init
  - pci_intr_establish
- Stop proceeding packets when the driver is likely
  to stop for graceful ifconfig down

Tested on Rangeley (I354) and KVM (e1000)
