Make it possible to write individual gain table entries. Allow gain table entries to be written outside gain table init. Add version-agnostic helpers for writing gain tables. Use the new TX gain table helpers during table init. Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
