Hello,
rc1 for Barrier Breaker when installed on Ubiquiti Bullet M 5GHz device
has disabled outdoor channels. Is it possible to change kernel settings to
enable following two options for kmod-ath, please?
CONFIG_ATH_USER_REGD=y
CONFIG_PACKAGE_ATH_DFS=y
Currently, these are not set and in countries requiring DFS before the
outdoor channels are activated, the latest versions are unusable.
Without CONFIG_PACKAGE_ATH_DFS set, only these channels are available:
