        syssrc/sys/dev/ic: i82557.c i82557var.h

Log Message:
Add support for the "CPUSaver" receive interrupt mitigating microcode
on the following PRO/100 chips:

        * i82558 step A4
        * i82558 step B0
        * i82559 step A0
        * i82559S step A
        * i82550
        * i82550 step C

The interrupt delay is configurable on all microcodable chips.  The
maximum "bundle" size (packet count) is configurable on all but the
i82558.

The microcode is enabled by setting IFF_LINK0 on the interface.

Derived from code in FreeBSD.
