Switch/"advanced functionality" questions are resurfacing often -
many devs probably know & hate that "HW-NAT" ticket
https://dev.openwrt.org/ticket/11779

There might be 2 interesting posts regarding current/future state and
development direction of In-Kernel drivers:

1) rejected in 2013: "net: phy: add Generic Netlink switch configuration API" 
link: http://lwn.net/Articles/571390/
The thread might be of (historical)/implementation interest

That thread mentions some other infrastructure in Kernel (Marvell DSA)
(that is not appropriate for OpenWrt according to devs)

2) since November 2014 there is a new switchdev api:
introduce rocker switch driver with hardware accelerated datapath api - phase 
1: bridge fdb offload
