Bonding device forbids slave device of different types under the same master. However, it is possible for a bonding master to change type during its lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND or the other way arround. The change of type requires device level multicast address cleanup because device level multicast addresses depend on the device type. The patch adds a call to dev_close() before the bonding master changes type and dev_open() just after that. In the example below I enslaved an IPoIB device (ib0) under bond0. Since each bonding master starts as device of type ARPHRD_ETHER by default, a change of type occurs when ib0 is enslaved. This is how /proc/net/dev_mcast looks like without the patch 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 01005e000116 5 bond0 1 0 01005e7ffffd 5 bond0 1 0 01005e000001 5 bond0 1 0 333300000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 333300000001 6 ib0 1 0 01005e000001 6 ib0 1 0 01005e7ffffd 6 ib0 1 0 01005e000116 6 ib0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff00000000000000000001 and this is how it looks like after the patch. 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 00ffffffff12601bffff00000000000000000001 5 bond0 1 0 00ffffffff12401bffff0000000000000ffffffd 5 bond0 1 0 00ffffffff12401bffff00000000000000000116 5 bond0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 00ffffffff12401bffff00000000000000000116 6 ib0 1 0 00ffffffff12401bffff0000000000000ffffffd 6 ib0 2 0 00ffffffff12401bffff00000000000000000001 6 ib0 2 0 00ffffffff12601bffff00000000000000000001 Signed-off-by: Moni Shoua <monis@voltaire.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.
