+ec_multi* of ethercom
+---------------------
+
+ec_multiaddrs and ec_multicnt of struct ethercom and items listed in
+ec_multiaddrs must be protected by ec_lock. The core of ethernet subsystem is
+already MP-safe, however, device drivers that use the data should also be fixed.
+A typical change should be to protect manipulations of the data via ETHER_*
+macros such as ETHER_FIRST_MULTI by ETHER_LOCK and ETHER_UNLOCK.
