Hardware NAT For LEDE

It should.
The story (base on what I see) is that Qualcomm has combined all their switch driver under QCA-SSDK
The switches are
GARUDA (AR8316)
ATHENA (AR8216)
SHIVA (AR8227/AR8228/AR8229)
HORUS (AR8263)
ISIS ((AR8325/AR8327/AR8328),without HNAT, AR8327N/AR8328N with HNAT)
ISISC (??)
DESS (Should be the new IPQ ARM Processors)
And the QCA-SSDK build targets are ALL-CHIP so it should be some sort of auto detect
If your router has the switches above it should be gd
