2018-07-07vxlan: fix default fdb entry netlink notify ordering during netdev createRoopa Prabhu
Problem: In vxlan_newlink, a default fdb entry is added before register_netdev. The default fdb creation function also notifies user-space of the fdb entry on the vxlan device which user-space does not know about yet. (RTM_NEWNEIGH goes before RTM_NEWLINK for the same ifindex). This patch fixes the user-space netlink notification ordering issue with the following changes: - decouple fdb notify from fdb create. - Move fdb notify after register_netdev. - Call rtnl_configure_link in vxlan newlink handler to notify userspace about the newlink before fdb notify and hence avoiding the user-space race.

2018-07-07vxlan: add new fdb alloc and create helpersRoopa Prabhu
- Add new vxlan_fdb_alloc helper - rename existing vxlan_fdb_create into vxlan_fdb_update: because it really creates or updates an existing fdb entry - move new fdb creation into a separate vxlan_fdb_create Main motivation for this change is to introduce the ability to decouple vxlan fdb creation and notify, used in a later patch.

2018-07-07liquidio: fix kernel panic when NIC firmware is older than 1.7.2Rick Farrington
Pre-1.7.2 NIC firmware does not support (and does not respond to) the "get speed" command which is sent by the 1.7.2 driver (for CN23XX-225 cards only) during modprobe. Due to a bug in older firmware (with respect to unknown commands), this unsupported command causes a cascade of errors that ends in a kernel panic.

2018-07-04igb: Add support for ETF offloadJesus Sanchez-Palencia
Implement HW offload support for SO_TXTIME through igb's Launchtime feature. This is done by extending igb_setup_tc() so it supports TC_SETUP_QDISC_ETF and configuring i210 so time based transmit arbitration is enabled. The FQTSS transmission mode added before is extended so strict priority (SP) queues wait for stream reservation (SR) ones. igb_config_tx_modes() is extended so it can support enabling/disabling Launchtime following the previous approach used for the credit-based shaper (CBS). As the previous flow, FQTSS transmission mode is enabled automatically by the driver once Launchtime (or CBS, as before) is enabled. Similarly, it's automatically disabled when the feature is disabled for the last queue that had it setup on. The driver just consumes the transmit times from the skbuffs directly, so no special handling is done in case an 'invalid' time is provided. We assume this has been handled by the ETF qdisc already.

2018-07-04igb: Only call skb_tx_timestamp after descriptors are readyJesus Sanchez-Palencia
Currently, skb_tx_timestamp() is being called before the Tx descriptors are prepared in igb_xmit_frame_ring(), which happens during either the igb_tso() or igb_tx_csum() calls. Given that now the skb->tstamp might be used to carry the timestamp for SO_TXTIME, we must only call skb_tx_timestamp() after the information has been copied into the Tx descriptors.
