Subject: [PATCH] bridge: Remove BR_PROXYARP flooding check code

From: Kyeyoon Park <kyeyoonp@...eaurora.org>

Because dropping broadcast packets for IEEE 802.11 Proxy ARP is more
selective than previously thought, it is better to remove the direct
dropping logic in the bridge code in favor of using the netfilter
infrastructure to provide more control on which frames get dropped. This
code was added in commit 958501163ddd ("bridge: Add support for IEEE
802.11 Proxy ARP").
