        src/sys/dev/pci: if_wm.c

Log Message:
Fix wm(4) input drop packet counter.

WMREG_RNBC is incremented when there is no available buffers in host
memory. However, ethernet controller can receive packets in such case
if there is space in phy's FIFO. That is, ethernet controller drops
packet only if there is no available buffers *and* there is no space
in phy's FIFO.
So, the number of dropped packets should be added WMREG_MPC only.
