* tipc: Eliminate improper use of TIPC_OK error codeAllan Stephens2008-07-15
| | | | | | | | | | | This patch corrects many places where TIPC routines indicated successful completion by returning TIPC_OK instead of 0. (The TIPC_OK symbol has the value 0, but it should only be used in contexts that deal with the error code field of a TIPC message header.)

* tipc: Fix race condition that could cause accept() to failAllan Stephens2008-07-15
| | | | | | | | | | | | | | This patch ensurs that accept() returns successfully even when the newly created socket is immediately disconnected by its peer. Previously, accept() would fail if it was unable to pass back the optional address info for the socket's peer before the socket became disconnected; TIPC now allows accept() to gather peer address information after disconnection. As a bonus, the revised code accesses the socket's port more efficiently, without the overhead incurred by a reference table lookup.

* tipc: Optimize pointer dereferencing when receiving stream dataAllan Stephens2008-07-15

* tipc: Remove unneeded parameter to tipc_createport_raw()Allan Stephens2008-07-15
| | | | | | | | | | This patch eliminates an unneeded parameter when creating a low-level TIPC port object. Instead of returning both the pointer to the port structure and the port's reference ID, it now returns only the pointer since the port structure contains the reference ID as one of its fields.

| | | | | | | | | | | | | | | | | | | | | | | | | | Adds netif_napi_del function which is used to remove the napi struct from the netdev napi_list in cases where CONFIG_NETPOLL was enabled. The motivation for adding this is to handle the case in which the number of queues on a device changes due to a configuration change. Previously the napi structs for each queue would be left in the list until the netdev was freed.
