2017-02-07net: ethernet: ti: cpsw: remove netif_trans_updateIvan Khoronzhuk
No need to update jiffies in txq->trans_start twice, it's supposed to be done in netdev_start_xmit() and anyway is re-written. Also, no reason to update trans time in case of an error. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-07bnxt_en: Add support for XDP_TX action.Michael Chan
Add dedicated transmit function and transmit completion handler for XDP. The XDP transmit logic and completion logic are different than regular TX ring. The TX buffer is recycled back to the RX ring when it completes. v3: Improved the buffer recyling scheme for XDP_TX. v2: Add trace_xdp_exception(). Add dma_sync.

2017-02-07bnxt_en: Refactor tx completion path.Michael Chan
XDP_TX requires a different function to handle completion. Add a function pointer to handle tx completion logic. Regular TX rings will be assigned the current bnxt_tx_int() for the ->tx_int() function pointer. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2017-02-07bnxt_en: Add a set of TX rings to support XDP.Michael Chan
Add logic for an extra set of TX rings for XDP. If enabled, this set of TX rings equals the number of RX rings and shares the same IRQ as the RX ring set. A new field bp->tx_nr_rings_xdp is added to keep track of these TX XDP rings. Adjust all other relevant functions to handle bp->tx_nr_rings_xdp.

2017-02-07bnxt_en: Add tx ring mapping logic.Michael Chan
To support XDP_TX, we need to add a set of dedicated TX rings, each associated with the NAPI of an RX ring. To assign XDP rings and regular rings in a flexible way, we add a bp->tx_ring_map[] array to do the remapping. The netdev txq index is stored in the new field txq_index so that we can retrieve the netdev txq when handling TX completions. In this patch, before we introduce XDP_TX, the mapping is 1:1. v2: Fixed a bug in bnxt_tx_int(). Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2017-02-07bnxt_en: Centralize logic to reserve rings.Michael Chan
Currently, bnxt_setup_tc() and bnxt_set_channels() have similar and duplicated code to check and reserve rx and tx rings. Add a new function bnxt_reserve_rings() to centralize the logic. This will make it easier to add XDP_TX support which requires allocating a new set of TX rings. Also, the tx ring checking logic in bnxt_setup_msix() can be removed. The rings have been reserved before hand. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-07bnxt_en: Use event bit map in RX path.Michael Chan
In the current code, we have separate rx_event and agg_event parameters to keep track of rx and aggregation events. Combine these events into an u8 event mask with different bits defined for different events. This way, it is easier to expand the logic to include XDP tx events.

2017-02-07bnxt_en: Refactor rx SKB function.Michael Chan
Minor refactoring of bnxt_rx_skb() so that it can easily be replaced by a new function that handles packets in a single page. Also, use a function pointer bp->rx_skb_func() to switch to a new function when we add the new mode in the next patch. Add a new field data_ptr that points to the packet data in the bnxt_sw_rx_bd structure. The original data field is changed to void pointer so that it can either hold the kmalloc'ed data or a page pointer. The last parameter of bnxt_rx_skb() which was the length parameter is changed to include the payload offset of the packet in the upper 16 bit. The offset is needed to support the rx page mode and is not used in this existing function. v3: Added a new data_ptr parameter to bp->rx_skb_func(). The caller has the option to modify the starting address of the packet. This will be needed when XDP with headroom support is added. v2: Changed the name of the last parameter to offset_and_len to make the code more clear.

2017-02-07net: qcom/emac: add ethool support for setting pause parametersTimur Tabi
To support setting the pause parameters, the driver can no longer just mirror the PHY. The set_pauseparam feature allows the driver to force the setting in the MAC, regardless of how the PHY is configured. This means that we now need to maintain an internal state for pause frame support, and so get_pauseparam also needs to be updated. If the interface is already running when the setting is changed, then the interface is reset. Note that if the MAC is configured to enable RX pause frame support (i.e. it transmits pause frames to throttle the other end), but the PHY is configured to block those frames, then the feature will not work. Also some buffer size initialization code into emac_init_adapter(), so that it lives with similar code, including the initializtion of pause frame support.

2017-02-07net: dsa: mv88e6xxx: Set the CMODE for mv88e6390 ports 9 & 10Andrew Lunn
Unlike most ports, ports 9 and 10 of the 6390X family have configurable PHY modes. Set the mode as part of adjust_link(). Ordering is important, because the SERDES interfaces connected to ports 9 and 10 can be split and assigned to other ports. The CMODE has to be correctly set before the SERDES interface on another port can be configured. Such configuration is likely to be performed in port_enable() and port_disabled(), called on slave_open() and slave_close(). The simple case is port 9 and 10 are used for 'CPU' or 'DSA'. In this case, the CMODE is set via a phy-mode in dsa_cpu_dsa_setup(), which is called early in the switch setup. When ports 9 or 10 are used as user ports, and have a fixed-phy, when the fixed fixed-phy is attached, dsa_slave_adjust_link() is called, which results in the adjust_link function being called, setting the cmode. The port_enable() will for other ports will be called much later. When ports 9 or 10 are used as user ports and have a real phy attached which does not use all the available SERDES interface, e.g. a 1Gbps SGMII, there is currently no mechanism in place to set the CMODE of the port from software. It must be hoped the stripping resistors are correct. At the same time, add a function to get the cmode. This will be needed when configuring the SERDES interfaces.

2017-02-07virtio_net: XDP support for adjust_headJohn Fastabend
Add support for XDP adjust head by allocating a 256B header region that XDP programs can grow into. This is only enabled when a XDP program is loaded. In order to ensure that we do not have to unwind queue headroom push queue setup below bpf_prog_add. It reads better to do a prog ref unwind vs another queue setup call. At the moment this code must do a full reset to ensure old buffers without headroom on program add or with headroom on program removal are not used incorrectly in the datapath. Ideally we would only have to disable/enable the RX queues being updated but there is no API to do this at the moment in virtio so use the big hammer. In practice it is likely not that big of a problem as this will only happen when XDP is enabled/disabled changing programs does not require the reset. There is some risk that the driver may either have an allocation failure or for some reason fail to correctly negotiate with the underlying backend in this case the driver will be left uninitialized. I have not seen this ever happen on my test systems and for what its worth this same failure case can occur from probe and other contexts in virtio framework.

For XDP use case and to allow ethtool reset tests it is useful to be able to use reset paths from contexts where rtnl lock is already held. This requries updating virtnet_set_queues and free_receive_bufs the two places where rtnl_lock is taken in virtio_net. To do this we use the following pattern, _foo(...) { do stuff } foo(...) { rtnl_lock(); _foo(...); rtnl_unlock()}; this allows us to use freeze()/restore() flow from both contexts.

2017-02-07ath9k: fix race condition in enabling/disabling IRQsFelix Fietkau
The code currently relies on refcounting to disable IRQs from within the IRQ handler and re-enabling them again after the tasklet has run. However, due to race conditions sometimes the IRQ handler might be called twice, or the tasklet may not run at all (if interrupted in the middle of a reset). This can cause nasty imbalances in the irq-disable refcount which will get the driver permanently stuck until the entire radio has been stopped and started again (ath_reset will not recover from this). Instead of using this fragile logic, change the code to ensure that running the irq handler during tasklet processing is safe, and leave the refcount untouched.

The problem was resolved by placing the struct bt_coexist_info at the head of each of those private areas.

2017-02-07rtlwifi: btcoexist: Convert halbtcoutsrc.c to use standard debuggingLarry Finger
The routines in btcoexist use different debugging routines than are used in the other drivers. This patch converts halbtcoutsrc.c to use the standard routines. It also deletes the definitions of the now-unused debugging macros, and turns on compilation of all the routines in btcoexist.
