PATCH 1/2 net/bonding: fix promiscuous and allmulticast state
Currently, promiscuous or allmulticast state of bonding port will not be passed to the new primary slave when active/standby switchover. It causes bugs in some scenario.
For example, promiscuous state of bonding port is off now, primary slave (called A) is off but secondary slave(called B) is on. Then active/standby switchover, promiscuous state of the bonding port is off, but the new primary slave turns to be B and its promiscuous state is still on. It is not consistent with bonding port. And this patch will fix it.

PATCH 2/2 net/bonding: fix reference count on mbufs
In reply to Min Hu (Connor)In bonding Tx broadcast mode, Packets should be sent by every slave, but only one mbuf exits. The solution is to increment reference count on mbufs, but it ignores multi segments.
This patch fixed it by adding reference for every segment in multi segments Tx scenario.
