2013-10-29net: mvmdio: doc: mvmdio now used by mv643xx_ethLeigh Brown1-5/+3

2013-10-29net: mvmdio: orion_mdio_ready: remove manual pollLeigh Brown1-21/+13
Replace manual poll of MVMDIO_SMI_READ_VALID with a call to orion_mdio_wait_ready. This ensures a consistent timeout, eliminates a busy loop, and allows for use of interrupts on systems that support them. Signed-off-by: Leigh Brown <leigh@solinno.co.uk> Signed-off-by: David S.

2013-10-29net: mvmdio: make orion_mdio_wait_ready consistentLeigh Brown1-22/+30
Amend orion_mdio_wait_ready so that the same timeout is used when polling or using wait_event_timeout. Set the timeout to 1ms. Replace udelay with usleep_range to avoid a busy loop, and set the polling interval range as 45us to 55us, so that the first sleep will be enough in almost all cases. Generate the same log message at timeout when polling or using wait_event_timeout. Signed-off-by: Leigh Brown <leigh@solinno.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-10-28virtio_net: migrate mergeable rx buffers to page frag allocatorsMichael Dalton1-58/+106
The virtio_net driver's mergeable receive buffer allocator uses 4KB packet buffers. For MTU-sized traffic, SKB truesize is > 4KB but only ~1500 bytes of the buffer is used to store packet data, reducing the effective TCP window size substantially. This patch addresses the performance concerns with mergeable receive buffers by allocating MTU-sized packet buffers using page frag allocators. If more than MAX_SKB_FRAGS buffers are needed, the SKB frag_list is used. Signed-off-by: Michael Dalton <mwdalton@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

While investigating on a recent vxlan regression, I found veth was using a zero features set for vxlan tunnels. We have to segment GSO frames, copy the payload, and do the checksum. This patch brings a ~200% performance increase We probably have to add hw_enc_features support on other virtual devices.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to igb, igbvf, i40e, ixgbe and ixgbevf. Dan Carpenter provides a patch for igbvf to fix a bug found by a static checker. If the new MTU is very large, then "new_mtu + ETH_HLEN + ETH_FCS_LEN" can wrap and the check on the next line can underflow. Wei Yongjun provides 2 patches, the first against igbvf adds a missing iounmap() before the return from igbvf_probe(). The second against i40e, removes the include <linux/version.h> because it is not needed. Carolyn provides a patch for igb to fix a call to set the master/slave mode for all m88 generation 2 PHY's and removes the call for I210 devices which do not need it. Stefan Assmann provides a patch for igb to fix an issue which was broke by: commit fa44f2f185f7f9da19d331929bb1b56c1ccd1d93 Author: Greg Rose <gregory.v.rose@intel.com> Date: Thu Jan 17 01:03:06 2013 -0800 igb: Enable SR-IOV configuration via PCI sysfs interface which breaks the reloading of igb when VFs are assigned to a guest, in several ways. Jacob provides a patch for ixgbe and ixgbevf. First, against ixgbe, cleans up ixgbe_enumerate_functions to reduce code complexity. The second, against ixgbevf, adds support for ethtool's get_coalesce and set_coalesce command for the ixgbevf driver. Yijing Wang provides a patch for ixgbe to use pcie_capability_read_word() to simplify the code. Emil provides a ixgbe patch to fix an issue where the logic used to detect changes in rx-usecs was incorrect and was masked by the call to ixgbe_update_rsc(). Don provides 2 patches for ixgbevf. First creates a new function to set PSRTYPE. The second bumps the ixgbevf driver version. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-10-22macvlan: resolve ENOENT errors on creationJohn Fastabend1-6/+5
After the commit below attempting to create macvlan devices was resulting in ENOENT errors, # ip link add link p3p2 type macvlan RTNETLINK answers: Invalid argument This happens because netdev_upper_dev_link() is called before register_netdevice() in the macvlan code. Through a call chain this results in a call to __netdev_adjacent_dev_insert() and finally a sysfs_create_link(). This requires the kobject of the macvlan to be registered which is done in register_netdevice(). If there is no kobject which is the case here the ENOENT error is seen on the command line. To resolve this move the netdev_upper_dev_link() call below the register_netdevice() call. This aligns with vlan driver flow. Regression introduced here, commit 5831d66e8097aedfa3bc35941cf265ada2352317 Author: Veaceslav Falico <vfalico@redhat.com> Date: Wed Sep 25 09:20:32 2013 +0200 net: create sysfs symlinks for neighbour devices CC: Veaceslav Falico <vfalico@redhat.com> CC: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Acked-by: Veaceslav Falico <vfalico@redhat.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

2013-10-22bonding: move bond-specific init after enslave happensVeaceslav Falico1-51/+14
As Jiri noted, currently we first do all bonding-specific initialization (specifically - bond_select_active_slave(bond)) before we actually attach the slave (so that it becomes visible through bond_for_each_slave() and friends). This might result in bond_select_active_slave() not seeing the first/new slave and, thus, not actually selecting an active slave. Fix this by moving all the bond-related init part after we've actually completely initialized and linked (via bond_master_upper_dev_link()) the new slave. Also, remove the bond_(de/a)ttach_slave(), it's useless to have functions to ++/-- one int. After this we have all the initialization of the new slave *before* linking, and all the stuff that needs to be done on bonding *after* it. It has also a bonus effect - we can remove the locking on the new slave init completely, and only use it for bond_select_active_slave().

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e only. Jesse provides 6 patches against i40e. First is a patch to reduce CPU utilization by reducing read-flush to read in the hot path. Next couple of patches resolve coverity issues reported by Hannes Frederic Sowa <hannes@stressinduktion.org>. Then Jesse refactored i40e to cleanup functions which used cpu_to_xxx(foo) which caused a lot of line wrapping. Mitch provides 2 i40e patches. First fixes a panic when tx_rings[0] are not allocated, his second patch corrects a math error when assigning MSI-X vectors to VFs. The vectors-per-vf value reported by the hardware already conveniently reports one less than the actual value. Shannon provides 5 patches against i40e. His first patch corrects a number of little bugs in the error handling of irq setup, most of which ended up panicing the kernel. Next he fixes the overactive IRQ issue seen in testing and allows the use of the legacy interrupt. Shannon then provides a cleanup of the arguments declared at the beginning of each function. Then he provides a patch to make sure that there are really rings and queues before trying to dump information in them. Lastly he simplifies the code by using an already existing variable. Catherine provides an i40e patch to bump the version. v2: - Remove unneeded parenthesis in patch 3 based on feedback from Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> - Fix patch description for patch 11 based on feedback from Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> ==================== Signed-off-by: David S.
