Thank you both for help.
I have tried to check on mikrotik site, but they somehow relate to connect mikrotik with their devices. As I have understood WDS depends on implementation of drivers and HW capabilities. I was trying to use same (or near same) HW (Atheros) on both sides, but I was unsuccessful to configure all to work properly.
It looks to me that mikrotik has made some different version of WDS than it is in regular linux driver (even openwrt), so they can not connect properly (they do connect, but no IP traffic is done).
I will analyse debianadmin site, it looks promissing, thank you....
