Bridge doesn't propagate rx_flags to lower-level devices.  It 
automatically set all lower devices to promisc mode.

So, in the second case above, eth2 and eth3 have to be in promisc, but
nothing else does.  I am not sure I understand Stefans notation though
wrt to how vmbr1.3000 and tap114i1 are configured.  Stefan,  can you
elaborate?
