Subject: PR/48104 CVS commit: src/sys/net
Date: Thu, 23 Jul 2015 10:52:34 +0000
Module Name: src
Committed By: ozaki-r

Modified Files:
src/sys/net: if_bridge.c
Log Message:
Fix PR 48104
So far bridge cannot receive frames via a member interface when the frames
come from another member interface. So when we assign an IP address to
a member interface, hosts connected to another member interface cannot
ping to the IP address. That behavior isn't expected. See PR 48104 for
more realistic examples of this issue.
The change does:
- drop M_PROMISC before ether_input, which allows a bridge member interface
to receive a frame coming from another bridge member interface
- receive broadcast/multicast frames via all bridge member interfaces,
which is required to receive IPv6 multicast packets destined to a
multicast group belonging to a bridge member interface that is different
from a packet arrival interface
roy@ helped testing of the fix, thanks!

Log Message:
Reflect a fix for bridge
Due to PR 48104, some tests of ping/ping6 were failed but the tests now
should be successful. So reverse atf_check.
Bonus: the fix for PR 48104 also fixes another uknown failure.
