2015-03-03i40e: Only enable TC0 for NIC partition typeNeerav Parikh
In case of MFP mode the driver was returning incorrect number of TCs for partitions that are not enabled for iSCSI. Though the driver does not configure these TCs in the Tx scheduler for the NIC partitions; it does use this map to setup the queue mappings. This patch fixes this and keeps all the NIC partitions to the default PF TC i.e. TC0.

2015-03-03i40e: Fix RSS size at init since default num queue calculation has changedAnjali Singhai Jain
With changes to default number of queue pairs that the interface comes up with from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate rss_size. We will now recalculate rss_size based on number of queues enabled in the VSI. Without this fix if the max_lan_msix < num_online_cpu we will be coming up with fewer queues but will be populating rss_size based on num_online_cpus. This will result in packets getting silently dropped because RSS LUT has queues that are not enabled.

2015-03-02Merge branch 'neigh_cleanups'David S. Miller
Eric W. Biederman says: ==================== Neighbour table and ax25 cleanups While looking at the neighbour table to what it would take to allow using next hops in a different address family than the current packets I found a partial resolution for my issues and I stumbled upon some work that makes the neighbour table code easier to understand and maintain. Long ago in a much younger kernel ax25 found a hack to use dev_rebuild_header to transmit it's packets instead of going through what today is ndo_start_xmit. When the neighbour table was rewritten into it's current form the ax25 code was such a challenge that arp_broken_ops appeard in arp.c and neigh_compat_output appeared in neighbour.c to keep the ax25 hack alive. With a little bit of work I was able to remove some of the hack that is the ax25 transmit path for ip packets and to isolate what remains into a slightly more readable piece of code in ax25_ip.c. Removing the need for the generic code to worry about ax25 special cases. After cleaning up the old ax25 hacks I also performed a little bit of work on neigh_resolve_output to remove the need for a dst entry and to ensure cached headers get a deterministic protocol value in their cached header. This guarantees that a cached header will not be different depending on which protocol of packet is transmitted, and it allows packets to be transmitted that don't have a dst entry. There remains a small amount of code that takes advantage of when packets have a dst entry but that is something different. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-03-02tipc: Don't use iocb argument in socket layerYing Xue
Currently the iocb argument is used to idenfiy whether or not socket lock is hold before tipc_sendmsg()/tipc_send_stream() is called. But this usage prevents iocb argument from being dropped through sendmsg() at socket common layer. Therefore, in the commit we introduce two new functions called __tipc_sendmsg() and __tipc_send_stream(). When they are invoked, it assumes that their callers have taken socket lock, thereby avoiding the weird usage of iocb argument.

However, that would lead to the inabilty to export skb->priority to userspace if desired.

2015-03-02net: bluetooth: compact struct bt_skb_cb by inlining struct hci_req_ctrlEyal Birger
struct hci_req_ctrl is never used outside of struct bt_skb_cb; Inlining it frees 8 bytes on a 64 bit system in skb->cb[] allowing the addition of more ancillary data.

2015-03-02pppoe: Use workqueue to die properly when a PADT is receivedSimon Farnsworth
When a PADT frame is received, the socket may not be in a good state to close down the PPP interface. The current implementation handles this by simply blocking all further PPP traffic, and hoping that the lack of traffic will trigger the user to investigate. Use schedule_work to get to a process context from which we clear down the PPP interface, in a fashion analogous to hangup on a TTY-based PPP interface. This causes pppd to disconnect immediately, and allows tools to take immediate corrective action. Note that pppd's rp_pppoe.so plugin has code in it to disable the session when it disconnects; however, as a consequence of this patch, the session is already disabled before rp_pppoe.so is asked to disable the session. The result is a harmless error message: Failed to disconnect PPPoE socket: 114 Operation already in progress This message is safe to ignore, as long as the error is 114 Operation already in progress; in that specific case, it means that the PPPoE session has already been disabled before pppd tried to disable it.
