Function request: raw options field in "Edit wifi record" menu

[hgot07]

I'd like to propose a "raw_options" function in the "Edit wifi record" menu.

Why needed?
There are some device/application-specific variants in the UCI wireless setting (/etc/config/wireless). It's not easy to cover all potential options as well as new ones by the GUI.

What is this?
The "raw_options" field is a simple, multi-line text box to be filled with a list of raw options.
The option(s) will be appended to the wifi-iface block, making it easy to add a wide variety of options (variants or new).
Nothing happens when this multi-line text box is left blank.

A Passpoint configuration example is shown below.

T raw_options

- option macaddr
option macaddr '62:0F:FF:52:31:00'
option iw_enabled '1'
option iw_interworking '1'
option iw_access_network_type '3'
option iw_internet '1'
option iw_disable_dgaf '1'
option iw_asra '0'
option iw_esr '0'
option iw_uesa '0'
option iw_venue_group '2'
option iw_venue_type '8'
option iw_hessid '94:83:FF:1D:7F:01'
list iw_roaming_consortium '000000'
list iw_venue_name 'eng:exampleLab'
list iw_venue_url '1:https ://example.com/'
option iw_network_auth_type '00'
option iw_ipaddr_type_availability '0c'
list iw_domain_name 'example.com'
option hs20 '1'
option hs20_oper_friendly_name 'eng:Example Lab'
option hs20_operating_class '517C'

The options with prepended minus (-) will be removed if existed in the openSOHO's built-in template, and other options will be appended simply as they are.

Benefits

• Absorb device/application-specific variations.
• Much more flexibility, allowing complex / experimental / development use cases.
• No need to bother openSOHO developers further with option variations and/or new functions.

Considerations will be much appreciated.

Could you point to a bit more information with regard to the Passpoint? I'm curious.

Appending to the existing config should be quite straightforward.
Removing/adjusting existing options will probably not appear soon since opensoho does not contain code to adjust already written configuration items.

Passpoint is a core technology used in the WBA OpenRoaming.

It's not only for OpenRoaming but a general one useful for personal and office use cases as well.

I used the Passpoint configuration as a good example of complex setting that suffers from some dialects / variations. The proposed function is universal not limited to this particular use case.

Regarding the removing / adjusting, the logic would use the template of wifi-iface block hard-coded in opensoho.go as the source, before pushing the config to the device. No need to read/modify the config existing on the device.
