[OpenWrt-Devel] [PATCH v2] authsae: Use kbit/s as mcast_rate unit like wpad

[Sven Eckelmann]

The OpenWrt wireless configuration for mcast_rate is defined as Kbit/s when
using wpa_supplicant for IBSS/802.11s and iw for unencrypted IBSS/802.11s.
But when using authsae, the unit for the same option is redefined as
Mbit/s. Better use the same unit for this option independent of the backend
which is used.

Old values for mcast_rate (< 1000) are still interpreted Mbit/s to avoid
problems during upgrades from older versions.
