Pull networking fixes from David Miller: 1) Don't halt the firmware in r8152 driver, from Hayes Wang. 2) Handle full sized 802.1ad frames in bnx2 and tg3 drivers properly, from Vlad Yasevich. 3) Don't sleep while holding tx_clean_lock in netxen driver, fix from Manish Chopra. 4) Certain kinds of ipv6 routes can end up endlessly failing the route validation test, causing it to be re-looked up over and over again. This particularly kills input route caching in TCP sockets. Fix from Hannes Frederic Sowa. 5) netvsc_start_xmit() has a use-after-free access to skb->len, fix from K Y Srinivasan. 6) Fix matching of inverted containers in ematch module, from Ignacy Gawędzki. 7) Aggregation of GRO frames via SKB ->frag_list for linear skbs isn't handled properly, regression fix from Eric Dumazet. 8) Don't test return value of ipv4_neigh_lookup(), which returns an error pointer, against NULL. From WANG Cong. 9) Fix an old regression where we mistakenly allow a double add of the same tunnel. Fixes from Steffen Klassert. 10) macvtap device delete and open can run in parallel and corrupt lists etc., fix from Vlad Yasevich. 11) Fix build error with IPV6=m NETFILTER_XT_TARGET_TPROXY=y, from Pablo Neira Ayuso. 12) rhashtable_destroy() triggers lockdep splats, fix also from Pablo. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (32 commits) bna: Update Maintainer Email r8152: disable power cut for RTL8153 r8152: remove clearing bp bnx2: Correctly receive full sized 802.1ad fragmes tg3: Allow for recieve of full-size 8021AD frames r8152: fix setting RTL8152_UNPLUG netxen: Fix bug in Tx completion path. netxen: Fix BUG "sleeping function called from invalid context" ipv6: remove rt6i_genid hyperv: Fix a bug in netvsc_start_xmit() net: stmmac: fix stmmac_pci_probe failed when CONFIG_HAVE_CLK is selected ematch: Fix matching of inverted containers. gro: fix aggregation for skb using frag_list neigh: check error pointer instead of NULL for ipv4_neigh_lookup() ip6_gre: Return an error when adding an existing tunnel. ip6_vti: Return an error when adding an existing tunnel. ip6_tunnel: Return an error when adding an existing tunnel. ip6gre: add a rtnl link alias for ip6gretap net/mlx4_core: Allow not to specify probe_vf in SRIOV IB mode r8152: fix the carrier off when autoresuming ...

2014-10-01bnx2: Correctly receive full sized 802.1ad fragmesVlad Yasevich
This driver, similar to tg3, has a check that will cause full sized 802.1ad frames to be dropped. The frame will be larger then the standard mtu due to the presense of vlan header that has not been stripped. The driver should not drop this frame and should process it just like it does for 802.1q.

When receiving a vlan-tagged frame that still contains a vlan header, the length of the packet will be greater then MTU+ETH_HLEN since it will account of the extra vlan header. TG3 checks this for the case for 802.1Q, but not for 802.1ad. As a result, full sized 802.1ad frames get dropped by the card. Add a check for 802.1ad protocol when receving full sized frames.

2014-09-30net/mlx4_core: Deprecate error message at ConnectX-2 cards startup to debugJack Morgenstein
ConnectX2 HCAs have max_mtu=4k and max_vl=8 vls. However, if you specify a 4K mtu, the max_vl supported for 4K is 4 vls. The driver at startup attempts to set a 4K mtu using the max_vl value obtained from QUERY_PORT. Since the max_vl value is 8 vls (which is supported up to 2K mtu size), the first attempt to set the mtl/vl port value will fail, generating the following error message in the log: mlx4_core 0000:06:00.0: command 0xc failed: fw status = 0x40 The driver then tries again, using mtu=4k, vls=4, and this succeeds. Since we do not want to have this error message always displayed at driver start when there are ConnectX2 HCAs on the host, we deprecate the error message for this specific command/input_modifier/opcode_modifier/fw-status to be debug.

2014-09-30net/mlx4_core: New init and exit flow for mlx4_coreMajd Dibbiny
In the new flow, we separate the pci initialization and teardown from the initialization and teardown of the other resources. __mlx4_init_one handles the pci resources initialization. It then calls mlx4_load_one to initialize the remainder of the resources. When removing a device, mlx4_remove_one is invoked. However, now mlx4_remove_one calls mlx4_unload_one to free all the resources except the pci resources. When mlx4_unload_one returns, mlx4_remove_one then frees the pci resources. The above separation will allow us to implement 'reset flow' in the future. It will also enable more EQs for VFs and is a pre-step to the modern API to enable/disable SRIOV. Also added nvfs; an integer array of size MLX4_MAX_PORTS + 1; to the mlx4_dev struct. This new field is used to avoid parsing the num_vfs module parameter each time the mlx4_restart_one is called.

2014-09-30bonding: make global bonding stats more reliableAndy Gospodarek
As the code stands today, bonding stats are based simply on the stats from the member interfaces. If a member was to be removed from a bond, the stats would instantly drop. This would be confusing to an admin would would suddonly see interface stats drop while traffic is still flowing. In addition to preventing the stats drops mentioned above, new members will now be added to the bond and only traffic received after the member was added to the bond will be counted as part of bonding stats. Bonding counters will also be updated when any slaves are dropped to make sure the reported stats are reliable. v2: Changes suggested by Nik to properly allocate/free stats memory. v3: Properly destroy workqueue and fix netlink configuration path. v4: Moved cached stats into bonding and slave structs as there does not seem to be a complexity/performance benefit to using alloc'd memory vs in-struct memory.

2014-09-29net: stmmac: fix stmmac_pci_probe failed when CONFIG_HAVE_CLK is selectedKweh, Hock Leong
When the CONFIG_HAVE_CLK is selected for the system, the stmmac_pci_probe will fail with dmesg: [ 2.167225] stmmaceth 0000:00:14.6: enabling device (0000 -> 0002) [ 2.178267] stmmaceth 0000:00:14.6: enabling bus mastering [ 2.178436] stmmaceth 0000:00:14.6: irq 24 for MSI/MSI-X [ 2.178703] stmmaceth 0000:00:14.6: stmmac_dvr_probe: warning: cannot get CSR clock [ 2.186503] stmmac_pci_probe: main driver probe failed [ 2.194003] stmmaceth 0000:00:14.6: disabling bus mastering [ 2.196473] stmmaceth: probe of 0000:00:14.6 failed with error -2 This patch fix the issue by breaking the dependency to devm_clk_get() as the CSR clock can be obtained at priv->plat->clk_csr from pci driver.

2014-09-29macvlan: add source modeMichael Braun
This patch adds a new mode of operation to macvlan, called "source". It allows one to set a list of allowed mac address, which is used to match against source mac address from received frames on underlying interface. This enables creating mac based VLAN associations, instead of standard port or tag based. The feature is useful to deploy 802.1x mac based behavior, where drivers of underlying interfaces doesn't allows that. Configuration is done through the netlink interface using e.g.: ip link add link eth0 name macvlan0 type macvlan mode source ip link add link eth0 name macvlan1 type macvlan mode source ip link set link dev macvlan0 type macvlan macaddr add 00:11:11:11:11:11 ip link set link dev macvlan0 type macvlan macaddr add 00:22:22:22:22:22 ip link set link dev macvlan0 type macvlan macaddr add 00:33:33:33:33:33 ip link set link dev macvlan1 type macvlan macaddr add 00:33:33:33:33:33 ip link set link dev macvlan1 type macvlan macaddr add 00:44:44:44:44:44 This allows clients with MAC addresses 00:11:11:11:11:11, 00:22:22:22:22:22 to be part of only VLAN associated with macvlan0 interface. Clients with MAC addresses 00:44:44:44:44:44 with only VLAN associated with macvlan1 interface. And client with MAC address 00:33:33:33:33:33 to be associated with both VLANs. Based on work of Stefan Gula <steweg@gmail.com> v8: last version of Stefan Gula for Kernel 3.2.1 v9: rework onto linux-next 2014-03-12 by Michael Braun add MACADDR_SET command, enable to configure mac for source mode while creating interface v10: - reduce indention level - rename source_list to source_entry - use aligned 64bit ether address - use hash_64 instead of addr[5] v11: - rebase for 3.14 / linux-next 20.04.2014 v12 - rebase for linux-next 2014-09-25 Signed-off-by: Michael Braun <michael-dev@fami-braun.de> Signed-off-by: David S.
