> The Raspberry Pi 3 shares the same SMSC LAN9514 chip as its predecessor, the Raspberry Pi 2, adding 10/100 Ethernet connectivity and four USB channels to the board. As before, the SMSC chip connects to the SoC via a single USB channel, acting as a USB-to-Ethernet adaptor and USB hub.

Not exactly, the BT/WiFi chip is apparently running via SDIO.
But yes, that doesn't help with the Ethernet situation. I don't get why Broadcom, when they already do a custom SoC, didn't include one or two MII lines and use a real Ethernet PHY instead.
The point still stands that a $30 router blows away a rpi in terms of network connectivity (which should matter for a router).
