CVS commit: src/sys/dev/ic

Module Name:    src

        src/sys/dev/ic: gem.c gemvar.h

Log Message:
Improve handling of receive overflows.  When we get an overflow, don't
reset the chip if we are still receiving packets.  Real overflows can
happen when network and CPU(s) are loaded, so the reset is not needed
in this case.
Add a counter to track receive overflows (when GEM_COUNTERS is defined).

This reverts some changes (always reset on overflow) from
PR port-sparc64/46260.
