Subject: [PATCH 1/3] bridge: Base the BR_PROXYARP decision on the target port flag
From: Kyeyoon Park <kyeyoonp@...eaurora.org>
When doing proxy ARP, instead of checking the bridge port flag for
BR_PROXYARP on the bridge port on which the frame was received, check
the bridge port flag of the bridge port to which the target device
belongs.
