2016-04-28Merge branch '40GbE' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-04-27 This series contains updates to i40e and i40evf. Alex Duyck cleans up the feature flags since they are becoming pretty "massive", the primary change being that we now build our features list around hw_encap_features. Added support for IPIP and SIT offloads, which should improvement in throughput for IPIP and SIT tunnels with the offload enabled. Mitch adds support for configuring RSS on behalf of the VFs, which removes the burden of dealing with different hardware interfaces from the VF drivers and improves future compatibility. Fix to ensure that we do not panic by checking that the vsi_res pointer is valid before dereferencing it, after which we can drink beer and eat peanuts. Shannon does come housekeeping in i40e_add_fdir_ethtool() in preparation for more cloud filter work. Added flexibility to the nvmupdate facility by adding the ability to specify an AQ event opcode to wait on after Exec_AQ request. Michal adds device capability which defines if an update is available and if a security check is needed during the update process. Kamil just adds a device id to support X722 QSFP+ device. Greg fixes an issue where a mirror rule ID may be zero, so do not return invalid parameter when the user passes in a zero for a rule ID. Adds support to steer packets to VSIs by VLAN tag alone while being in promiscuous mode for multicast and unicast MAC addresses. Jesse fixes the driver from offloading the VLAN tag into the skb any time there was a VLAN tag and the hardware stripping was enabled, to making sure it is enabled before put_tag. v2: Dropped patch 8 ("i40e: Allow user to change input set mask for flow director") while Kiran reworks a more generalized solution based on feedback from David Miller. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-28net: w5100: support W5500Akinobu Mita
This adds support for W5500 chip. W5500 has similar register and memory organization with W5100 and W5200. There are a few important differences listed below but it is still possible to share common code with W5100 and W5200. * W5500 register and memory are organized by multiple blocks. Each one is selected by 16bits offset address and 5bits block select bits. But the existing register access operations take u16 address. This change extends the addess by u32 address and put offset address to lower 16bits and block select bits to upper 16bits. This change also adds the offset addresses for socket register and TX/RX memory blocks to the driver private data structure in order to reduce conditional switches for each chip. * W5500 has the different register offset for socket interrupt mask register. Newly added internal functions w5100_enable_intr() and w5100_disable_intr() take care of the diffrence. * W5500 has the different register offset for retry time-value register. But this register is only used to verify that the reset value is correctly read at initialization. So move the verification to w5100_hw_reset() which already does different things for different chips.

2016-04-26devpts: more pty driver interface cleanupsLinus Torvalds
This is more prep-work for the upcoming pty changes. Still just code cleanup with no actual semantic changes. This removes a bunch pointless complexity by just having the slave pty side remember the dentry associated with the devpts slave rather than the inode. That allows us to remove all the "look up the dentry" code for when we want to remove it again. Together with moving the tty pointer from "inode->i_private" to "dentry->d_fsdata" and getting rid of pointless inode locking, this removes about 30 lines of code. Not only is the end result smaller, it's simpler and easier to understand. The old code, for example, depended on the d_find_alias() to not just find the dentry, but also to check that it is still hashed, which in turn validated the tty pointer in the inode. That is a _very_ roundabout way to say "invalidate the cached tty pointer when the dentry is removed". The new code just does dentry->d_fsdata = NULL; in devpts_pty_kill() instead, invalidating the tty pointer rather more directly and obviously. Don't do something complex and subtle when the obvious straightforward approach will do. The rest of the patch (ie apart from code deletion and the above tty pointer clearing) is just switching the calling convention to pass the dentry or file pointer around instead of the inode.

2016-04-26net/mlx5e: Improve set features ndo resiliencyGal Pressman
In current mlx5e ndo_set_features implementation, setting some features can success while others can fail. Today, we return one error code which doesn't reflect the current features status of the netdev at the end of the ndo callback. Set netdev->features with features which were successfully set in order to keep the current status in case of failure. For this purpose, define new Macro to set/unset specific feature in netdev->features. This patch introduces a mechanism that uses feature handlers for each feature. Set features will call a generic handler, which will then call a specific handler in his turn and update netdev->features according to it's return value. Each specific handler is responsible to perform driver specific actions, and updating params if needed.

2016-04-26net/mlx5e: Statistics handling refactoringGal Pressman
Redesign ethtool statistics handling and reporting in the driver: 1. Move counters to a separate file (en_stats.h). 2. Remove unnecessary dependencies between stats and strings. 3. Use counter descriptors which hold a name and offset for each counter, and will be used to decide which counters will be exposed. For example when adding a new software counter to ethtool, instead of: 1. Add to stats struct. 2. Add to strings struct in the same order. 3. Change macro defining number of software counters. The only thing needed is to link the new counter to a counter descriptor. VPort counters are a set of hardware traffic counters created automatically for each virtual port opened. PPort counters are a set of counters describing per physical port performance statistics. These counters are gathered from hardware register and divided to groups according to different protocols.

If macvlan_common_newlink fails in register_netdevice after macvlan_init then it decrements port->count twice, first in macvlan_uninit (from register_netdevice or rollback_registered) and then again in macvlan_common_newlink. A similar problem may exist in the ipvlan driver. This patch consolidates modifications to port->count into macvlan_init and macvlan_uninit (thanks to Eric Biederman for suggesting this approach). v3: remove macvtap specific bits.

2016-04-26qed: Add vport WFQ configuration APIsManish Chopra
This patch adds relevant APIs needed to configure WFQ (Weighted fair queueing) values for the vports. WFQ configuration is used per vport basis when minimum bandwidth update/configuration is notified to the PF by the management firmware.

2016-04-26cxgb4: Don't assume FW_PORT_CMD reply is always port info msgHariprasad Shenai
The firmware can send a set of asynchronous replies through FW_PORT_CMD with DCBX information when that's negotiated with the Link Peer. The old code always assumed that a FW_PORT_CMD reply was always a Get Port Information message. This change conditionalizes the code to only handle the Get Port Information messages and throws a warning if we don't understand what we've been given. Also refactor t4_handle_fw_rpl() so that core functionality performed by t4_handle_get_port_info() for a specified port.

2016-04-26cxgb4: Avoids race and deadlock while freeing tx descriptorHariprasad Shenai
There could be race between t4_eth_xmit() and t4_free_sge_resources() while freeing tx descriptors, take txq lock in t4_free_sge_resources(). We need to stop the xmit frame path which runs in bottom half context while unloading the driver using _bh variant of the lock. This is to prevent the deadlock between xmit and driver unload.
