GetState
No input, returns an output u32.
sdknso implements this by returning the u32, with 0 being returned on error / when service isn't initialized.
GetNetworkInfo
Takes a type-0x1A output buffer containing a #NetworkInfo.
GetIpv4Address
No input, returns an output #Ipv4Address and a #SubnetMask.
GetDisconnectReason
No input, returns an output s16.
sdknso implements this by returning the s16 as a s32, with -1 being returned on error.
GetSecurityParameter
No input, returns an output #SecurityParameter.
GetNetworkConfig
No input, returns an output #NetworkConfig.
AttachStateChangeEvent
No input, returns an output Event handle.
sdknso uses EventClearMode=1 with this. sdknso will Abort if this cmd fails.
