I tried to bridge a wireless interface to a wired Ethernet interface,
and it failed with "Operation not supported."
Looking at the kernel code, it seems like this is intentional. I
noticed the following in br_add_if:
/* No bridging devices that dislike that (e.g. wireless) */
if (dev->priv_flags & IFF_DONT_BRIDGE)
return -EOPNOTSUPP;
I'm curious to know why this is not supported.

[Bridge] no wireless interfaces?

Because 802.11a/b/g/n does odd things with mac headers which make bridging them sometimes not work as expected.
