There was. Unfortunately it faild:

There is or was a 100 MBit/s or 1 GBit/s Ethernet chip that used a build
in MIPS core as controler.
The DEC DEF[QTEP]A FDDI card uses a M68k to implement the complex SMT
(Station MangemenT) in "hardware". Similar for the SGI GIO FDDI cards,
they are driven by an AMD 29k.
The Symbios / NCR SCSI chips have some sort of RISC core inside. I saw
DEC PCI DSSI cards with 53C825 on them. So DEC rewrote the firmware of
that RISC core to implement DSSI instead of SCSI. (AFAIK DSSI and SCSI
are quite different as DSSI is just a cheap parallel physical transport
for CI...)
