2018-03-26net: Drop NETDEV_UNREGISTER_FINALKirill Tkhai4-12/+4
Last user is gone after bdf5bd7f2132 "rds: tcp: remove register_netdevice_notifier infrastructure.", so we can remove this netdevice command. This allows to delete rtnl_lock() in netdev_run_todo(), which is hot path for net namespace unregistration. dev_change_net_namespace() and netdev_wait_allrefs() have rcu_barrier() before NETDEV_UNREGISTER_FINAL call, and the source commits say they were introduced to delemit the call with NETDEV_UNREGISTER, but this patch leaves them on the places, since they require additional analysis, whether we need in them for something else.

2018-03-26net: Make NETDEV_XXX commands enum { }Kirill Tkhai3-47/+57
This patch is preparation to drop NETDEV_UNREGISTER_FINAL. Since the cmd is used in usnic_ib_netdev_event_to_string() to get cmd name, after plain removing NETDEV_UNREGISTER_FINAL from everywhere, we'd have holes in event2str[] in this function. Instead of that, let's make NETDEV_XXX commands names available for everyone, and to define netdev_cmd_to_name() in the way we won't have to shaffle names after their numbers are changed.

2018-03-23ixgbe: tweak page counting for XDP_REDIRECTBjörn Töpel1-3/+4
The current page counting scheme assumes that the reference count cannot decrease until the received frame is sent to the upper layers of the networking stack. This assumption does not hold for the XDP_REDIRECT action, since a page (pointed out by xdp_buff) can have its reference count decreased via the xdp_do_redirect call. To work around that, we now start off by a large page count and then don't allow a refcount less than two.

2018-03-23ixgbevf: Add support for XDP_TX actionTony Nguyen3-32/+294
This implements the XDP_TX action which is modeled on the ixgbe implementation. However instead of using CPU id to determine which XDP queue to use, this uses the received RX queue index, which is similar to i40e. Doing this eliminates the restriction that number of CPUs not exceed number of XDP queues that ixgbe has. Also, based on the number of queues available, the number of TX queues may be reduced when an XDP program is loaded in order to accommodate the XDP queues.

2018-03-23ixgbe: no need for ipsec csum feature checkShannon Nelson1-6/+0
With the patch commit f8aa2696b4af ("esp: check the NETIF_F_HW_ESP_TX_CSUM bit before segmenting") we no longer need to protect ourself from checksum offload requests on IPsec packets, so we can remove the check in our .ndo_features_check callback.

2018-03-23ixgbe: fix read-modify-write in x550 phy setupPaul Greenwalt1-2/+2
Replaced an assignment operation with an OR operation. The variable assignment was overwriting the value read from the PHY register. The OR operation sets only the intended register bits. The bits that were being overwritten are reserved, so the assignment had no functional impact.
