Only the old(er)/cheap(er) ones.  Most recent
SoCs that are being used in consumer routers
have internal switching capabilities that can be
used along with hardware NAT support (a
L2/L3/L4 multilayer design), in addition to
integrated WiFi.  And the reason for using
these SoCs is, of course, money.  A single
SoC that integrates everything results in a
cheaper/faster to engineer and certify solution.
It also means when the SoC vendors S/RDK
turns out to have a VULN it impacts a lot of
devices from different vendors since they all
used the same base.  Qualcomm and
Broadcom are some big manufactures of
such SoCs.
