2005-07-28[PATCH] [IPoIB] Handle sending of unicast RARP responsesHal Rosenstock
RARP replies are another valid case where IPoIB may need to send a unicast packet with no neighbour structure. Signed-off-by: Hal Rosenstock <halr@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-07-28[PATCH] [IB/cm]: Correct CM port redirect reject codesRoland Dreier
Reject code 24 is port and CM redirection, not just port redirection. Port redirection alone is code 25. Therefore we should rename code 24 to IB_CM_REJ_PORT_CM_REDIRECT and use IB_CM_REJ_PORT_REDIRECT for code 25. Signed-off-by: Roland Dreier <rolandd@cisco.com>
