ib/verbs: add multicast block loopback capability to the ib device.
This patch adds a capability flag for blocking multicast loopback
packets in an ib device.
This patch also adds a creation flag for QPs:
IB_QP_CREATE_MULTICAST_BLOCK_LOOPBACK, which means that when attaching
this QP, the multicast packets loopback block bit will be turned on.
Signed-off-by: Ron Livne <[EMAIL PROTECTED]>
Changes in v2:
IB_QP_BLOCK_LOOPBACK QP creation flag in version 1, is now called
IB_QP_CREATE_MULTICAST_BLOCK_LOOPBACK.
