Sercomm H-500s is a BCM63268 with 128M, internal and external (Quantenna) wifi and external BCM53134S switch. This device is already supported in bcm63xx target, so more information can be found in https://openwrt.org/toh/sercomm/h500-s. It's a perfect example of a device with internal and external switch coexistance since most devices only have ports on one of the switches but not both of them.

Subject: [PATCH] net: dsa: b53: mdio: add support for BCM53134

Add support for the BCM53134 Ethernet switch in the existing b53 dsa driver.
|
|
The BCM53134 is very familiar to the BCM58XX series.
