jow is the maintainer for iwinfo, as said in its package Makefile.


FYI, I noticed the recent forum discussion and modified the propsed patch for 
my own builds by adding chip ID also for QCA9984, enabling proper recognition 
for some of the ipq806x devices like R7800.

It would be great to add more new wifi chips to the iwinfo database, so that 
more routers would have properly named radios.

Additionally, LuCI could be enhanced to show the correct radio chip also on 
the router overview page, not only in the network/wifi page. network/wifi has 
been calling iwinfo hardware_type, but router overview has skipped that and 
has only shown "Generic" as set by wifidev.get_i18n

The proper ID could be enabled with a small change to luci-base package:

I will likely do a LuCI PR about that and discuss it with jow. (Not quite 
sure if there performance issues in adding that iwinfo call to the repeatedly 
refreshed overvie page)
