Packets, typically broadcast packets, arriving on the inactive interface
are dropped.  Older kernels just dropped them silently, newer kernels
record them.  This is nice, because if you have a host on the network
broadcasting garbage to the network you'll see a lot of dropped packets.
You're getting just over 3% dropped packets which is a little higher than I
would consider usual, but not unreasonable on a busy network.

You're logging martians and do seem to have quite a lot which suggests that
there is something odd going on.  Those martians are a little worrying: you
really shouldn't see those, they don't look at all right.  The LL header
includes the MAC address of the sending machine, that might help you track
them down.
