2015-03-06switchdev: add IPv4 fib ndo ops wrappersScott Feldman2-0/+58
Add IPv4 fib ndo wrapper funcs and stub them out for now. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-06netdevice: add IPv4 fib add/del opsScott Feldman1-0/+22
Add two new ndo ops for IPv4 fib offload support, add and del. Add uses modifiy semantics if fib entry already offloaded. Drivers implementing the new ndo ops will return err<0 if programming device fails, for example if device's tables are full. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S.

Using napi_complete_done() instead of napi_complete() allows us to use /sys/class/net/ethX/gro_flush_timeout GRO layer can aggregate more packets if the flush is delayed a bit, without having to set too big coalescing parameters that impact latencies.

2015-03-06net: dsa: extract dsa switch tree setup and removalFlorian Fainelli1-39/+52
Extract the core logic that setups a 'struct dsa_switch_tree' and removes it, update dsa_probe() and dsa_remove() to use the two helper functions. This will be useful to allow for other callers to setup this structure differently. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-06net: dsa: let switches specify their tagging protocolFlorian Fainelli2-2/+8
In order to support the new DSA device driver model, a dsa_switch should be able to advertise the type of tagging protocol supported by the underlying switch device.

Split the part of dsa_switch_setup() which is responsible for allocating and initializing a 'struct dsa_switch' and the part which is doing a given switch device setup and slave network device creation. This is a preliminary change to allow a separate caller of dsa_switch_setup_one() which may have externally initialized the dsa_switch structure, outside of dsa_switch_setup().

In preparation for allowing a different model to register DSA switches, update dsa_of_probe() and dsa_probe() to return -EPROBE_DEFER where appropriate. Failure to find a phandle or Device Tree property is still fatal, but looking up the internal device structure associated with a Device Tree node is something that might need to be delayed based on driver probe ordering.

timewait sockets now share a common base with established sockets. inet_twsk_diag_dump() can use inet_diag_bc_sk() instead of duplicating code, granted that inet_diag_bc_sk() does proper userlocks initialization. twsk_build_assert() will catch any future changes that could break the assumptions.

If we cannot get enough MSI/X vectors, fall back to the minimum required: 1 per adapter rx channel.

2015-03-05bridge: Extend Proxy ARP design to allow optional rules for Wi-FiJouni Malinen7-8/+22
This extends the design in commit 958501163ddd ("bridge: Add support for IEEE 802.11 Proxy ARP") with optional set of rules that are needed to meet the IEEE 802.11 and Hotspot 2.0 requirements for ProxyARP. The previously added BR_PROXYARP behavior is left as-is and a new BR_PROXYARP_WIFI alternative is added so that this behavior can be configured from user space when required. In addition, this enables proxyarp functionality for unicast ARP requests for both BR_PROXYARP and BR_PROXYARP_WIFI since it is possible to use unicast as well as broadcast for these frames. The key differences in functionality: BR_PROXYARP: - uses the flag on the bridge port on which the request frame was received to determine whether to reply - block bridge port flooding completely on ports that enable proxy ARP BR_PROXYARP_WIFI: - uses the flag on the bridge port to which the target device of the request belongs - block bridge port flooding selectively based on whether the proxyarp functionality replied Signed-off-by: Jouni Malinen <jouni@codeaurora.org> Signed-off-by: David S.

1.

Add bcmgenet_tx_ring->clean_ptr - index of the next TxCB to be cleaned - incremented as TxCBs/TxBDs are processed - value always in range [ring->cb_ptr, ring->end_ptr] 3. Fix incrementing of dev->stats.tx_packets - should be incremented only when tx_cb_ptr->skb != NULL These changes simplify __bcmgenet_tx_reclaim(). Furthermore, Tx ring size can now be any value.

This change updates the fib_table_lookup function so that it is in sync with the fib_find_node function in terms of the explanation for the index check based on the bits value. I have also updated it from doing a mask to just doing a compare as I have found that seems to provide more options to the compiler as I have seen it turn this into a shift of the value and test under some circumstances. In addition I addressed one minor issue in which we kept computing the key ^ n->key when checking the fib aliases. I pulled the xor out of the loop in order to reduce the number of memory reads in the lookup. As a result we should save a couple cycles since the xor is only done once much earlier in the lookup.

2015-03-04fib_trie: Update insert and delete to make use of tp from find_nodeAlexander Duyck1-142/+95
This change makes it so that the insert and delete functions make use of the tnode pointer returned in the fib_find_node call. By doing this we will not have to rely on the parent pointer in the leaf which will be going away soon. Signed-off-by: Alexander Duyck <alexander.h.duyck@redhat.com> Signed-off-by: David S.

2015-03-04fib_trie: Fib find node should return parentAlexander Duyck1-18/+24
This change makes it so that the parent pointer is returned by reference in fib_find_node. By doing this I can use it to find the parent node when I am performing an insertion and I don't have to look for it again in fib_insert_node.

2015-03-04fib_trie: Fib walk rcu should take a tnode and key instead of a trie and a leafAlexander Duyck1-96/+120
This change makes it so that leaf_walk_rcu takes a tnode and a key instead of the trie and a leaf. The main idea behind this is to avoid using the leaf parent pointer as that can have additional overhead in the future as I am trying to reduce the size of a leaf down to 16 bytes on 64b systems and 12b on 32b systems.

2015-03-04fib_trie: Only resize tnodes once instead of on each leaf removal in fib_table_flushAlexander Duyck1-63/+78
This change makes it so that we only call resize on the tnodes, instead of from each of the leaves. By doing this we can significantly reduce the amount of time spent resizing as we can update all of the leaves in the tnode first before we make any determinations about resizing. As a result we can simply free the tnode in the case that all of the leaves from a given tnode are flushed instead of resizing with each leaf removed.

2015-03-04be2net: implement .sriov_configure() PCI callbackVasundhara Volam2-65/+107
This patch implements the .sriov_configure() PCI method to allow for runtime enabling/disabling of VFs. The module param "num_vfs" is now deprecated. At the time of driver load the PF-pool resources are allocated to the PF. When the user enables VFs, the resources are then re-distributed across PFs and VFs based on the number of VFs enabled.

2015-03-04be2net: re-distribute SRIOV resources allowed by FWVasundhara Volam4-38/+141
When SR-IOV is enabled in the adapter, the FW distributes resources evenly across the PF and it's VFs. This is currently done only for some resources. This patch adds support for a new cmd that queries the FW for the list of resources for which the distribution is allowed and distributes them accordingly.

2015-03-04be2net: avoid creating the non-RSS default RXQ if FW allows toVasundhara Volam5-24/+41
On BE2, BE3 and Skhawk-R chips one non-RSS (called "default") RXQ was needed to receive non-IP traffic. Some FW versions now export a capability called IFACE_FLAGS_DEFQ_RSS where this requirement doesn't hold. On such FWs the driver now does not create the non-RSS default queue. This prevents wasting one RXQ per VF. Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2015-03-04sh_eth: Mitigate lost statistics updatesBen Hutchings1-12/+25
The statistics registers have write-clear behaviour, which means we will lose any increment between the read and write. Mitigate this by only clearing when we read a non-zero value, so we will never falsely report a total of zero. This also saves time as we only handle error statistics here and they won't often be incremented. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S.
