This is a different component - the nic_bridge. The exception does occur in
nic_drv.

I don't know what you mean by "unexpected" - the nic_drv always expects packets
from the ethernet. To forward these packets to its single client, it has to
allocate a buffer and a packet descriptor in the incoming packet stream. For
some reason this fails, mostly because the client got stuck and does no longer
acknowledge incoming packets resulting in failed allocations for further
packets.

Would you mind to share your changes as a Github branch. I can't promise
anything because of vacation time but if a have a minute the next days I might
have a look.
