2017 | * hostapd_interface_init_bss - Read configuration file and init BSS data | |
2018 | * | |
2019 | * This function is used to parse configuration file for a BSS. This BSS is | |
2020 | * added to an existing interface sharing the same radio (if any) or a new | |
2021 | * interface is created if this is the first interface on a radio. This | |
2022 | * allocate memory for the BSS. No actual driver operations are started. | |
2023 | * | |
2024 | * This is similar to hostapd_interface_init(), but for a case where the | |
2025 | * configuration is used to add a single BSS instead of all BSSes for a radio. | |
