Michal Soltys 3c963a3306 bonding: fix PACKET_ORIGDEV regression ... This patch fixes a subtle PACKET_ORIGDEV regression which was a side effect of fixes introduced by: 6a9e461f6f bonding: pass link-local packets to bonding master also. ... to: b89f04c61e bonding: deliver link-local packets with skb->dev set to link that packets arrived on While 6a9e461f6f restored pre-b89f04c61efe presence of link-local packets on bonding masters (which is required e.g. by linux bridges participating in spanning tree or needed for lab-like setups created with group_fwd_mask) it also caused the originating device information to be lost due to cloning. Maciej Żenczykowski proposed another solution that doesn't require packet cloning and retains original device information - instead of returning RX_HANDLER_PASS for all link-local packets it's now limited only to packets from inactive slaves. At the same time, packets passed to bonding masters retain correct information about the originating device and PACKET_ORIGDEV can be used to determine it. This elegantly solves all issues so far: - link-local packets that were removed from bonding masters - LLDP daemons being forced to explicitly bind to slave interfaces - PACKET_ORIGDEV having no effect on bond interfaces Fixes: 6a9e461f6f (bonding: pass link-local packets to bonding master also.)
