The sh_eth_cpu_data::chip_reset() method always resets using ARSTR and this register is always located at the start of the TSU register region. Therefore, we can only call this method if we know TSU is there and thus simplify the probing code a bit... Signed-off-by:

Merge tag 'wireless-drivers-next-for-davem-2018-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for 4.16 Here are patches which have been accumulating over the holidays and after the New Year. Business as usual and nothing special really standing out. But what's noteworthy here is that Larry Finger is stepping down as the rtlwifi maintainer. He has been maintaining rtlwifi since it was applied back in 2010 in commit 0c817338 ("rtl8192ce: Add new driver") and it has been no easy role trying to juggle between the vendor, demanding upstream community and users. So big thank you to Larry for all his efforts! ath10k * more preparation work for wcn3990 support * add memory dump to firmware coredump files wil6210 * support scheduled scan * support 40-bit DMA addresses qtnfmac * support MAC address based access control * support for radar detection and Channel Availibility Check (CAC) mwifiex * firmware coredump for usb devices rtlwifi * Larry Finger steps down as the maintainer and Ping-Ke Shih becomes the new maintainer * add debugfs interfaces to dump register and btcoex status, and also write registers and h2c ==================== Signed-off-by:

The Gemini ethernet has been around for years as an out-of-tree patch used with the NAS boxen and routers built on StorLink SL3512 and SL3516, later Storm Semiconductor, later Cortina Systems. These ASICs are still being deployed and brand new off-the-shelf systems using it can easily be acquired. The full name of the IP block is "Net Engine and Gigabit Ethernet MAC" commonly just called "GMAC". The hardware block contains a common TCP Offload Enginer (TOE) that can be used by both MACs. The current driver does not use it. Cc: Tobias Waldvogel <tobias.waldvogel@gmail.com> Signed-off-by:

In commit 232d07b7 ("tipc: improve groupcast scope handling") we inadvertently broke non-group multicast transmission when changing the parameter 'domain' to 'scope' in the function tipc_nametbl_lookup_dst_nodes(). We missed to make the corresponding change in the calling function, with the result that the lookup always fails. A closer anaysis reveals that this parameter is not needed at all. Non-group multicast is hard coded to use CLUSTER_SCOPE, and in the current implementation this will be delivered to all matching destinations except those which are published with NODE_SCOPE on other nodes. Since such publications never will be visible on the sending node anyway, it makes no sense to discriminate by scope at all. We now remove this parameter altogether. Signed-off-by:

Since net could be obtained from RCU lists, and there is a race with net destruction, the patch converts net::count to refcount_t. This provides sanity checks for the cases of incrementing counter of already dead net, when maybe_get_net() has to used instead of get_net(). Drivers: allyesconfig and allmodconfig are OK.

I see two issues with parameter new_link: 1. It's not needed. See also phy_interrupt(), works w/o this parameter. phy_mac_interrupt sets the state to PHY_CHANGELINK and triggers the state machine which then calls phy_read_status. And phy_read_status updates the link state. 2. phy_mac_interrupt is used in interrupt context and getting the link state may sleep (at least when having to access the PHY registers via MDIO bus). So let's remove it. Signed-off-by:

__phy_modify would return the old value of the register before it was modified. Thus on success, it does not return 0, but a positive value. Thus functions using phy_modify, which is a wrapper around __phy_modify, can start returning > 0 on success, rather than 0. As a result, breakage has been noticed in various places, where 0 was assumed. Code inspection does not find any current location where the return of the old value is currently used. So have __phy_modify return 0 on success. When there is a real need for the old value, either a new accessor can be added, or an additional parameter passed. Fixes: fea23fb5 ("net: phy: convert read-modify-write to phy_modify()") Fixes: 2b74e5be ("net: phy: add phy_modify() accessor") Reported-by:

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-01-12 This series contains updates to ixgbe, fm10k and net core. Alex updates the driver to remove a duplicate MAC address check and verifies that we have not run out of resources to configure a MAC rule in our filter table. Also do not assume that dev->num_tc was populated and configured with the driver, since it can be configured via mqprio without any hardware coordination. Fixed the recording of stats for MACVLAN in ixgbe and fm10k instead of recording the receive queue on MACVLAN offloaded frames. When handling a MACVLAN offload, we should be stopping/starting traffic on our own queues instead of the upper devices transmit queues. Fixed possible race conditions with the MACVLAN cleanup with the interface cleanup on shutdown. With the recent fixes to ixgbe, we can cap the number of queues regardless of accel_priv being in use or not, since the actual number of queues are being reported via real_num_tx_queues. Tony fixes up the kernel documentation for ixgbe and ixgbevf to resolve warnings when W=1 is used. ==================== Signed-off-by: -

Jiri Pirko says: ==================== mlxsw: Offload PRIO qdisc Nogah says: Add an offload support for PRIO qdisc for mlxsw driver. PRIO qdisc is being offloaded by using ndo_setup_tc. It has three commands, to set or tune the qdisc, to remove it and to get its stats. Like RED offloading, offloading this qdisc is not enforced on the driver and determining its offload state is done in the dump action, when the stats are being updated. In the driver, offloading of PRIO is supported as root qdisc only. It supports only priorities 0-7 (the range that is used by the current static mapping of DSCP to skb prio and by 1:1 PCP values mapping) and up to 8 bands. Patches 1-2 offload DSCP to priority mapping in the mlxsw_sp driver. Patch 3 adds offload support for PRIO qdisc. Patches 4-5 Add PRIO offload support in the mlxsw_sp driver. --- v1->v2: - Patch 1/5: - Rewrite patch msg - Patch 3/5: - Send all the qstats in the replace command (and not just backlog) - Patch 5/5: - Align with the changes from 3/5 - Move backlog to the generic qdisc stats struct - Delete extra newline ==================== Signed-off-by: -

Support basic stats for PRIO qdisc, which includes tx packets and bytes count, drops count and backlog size. The rest of the stats are irrelevant for this qdisc offload. Since backlog is not only incremental but reflecting momentary value, in case of a qdisc that stops being offloaded but is not destroyed, backlog value needs to be updated about the un-offloading. For that reason an unoffload function is being added to the ops struct. Signed-off-by:

Add support for offloading PRIO qdisc as root qdisc. The support is for up to 8 bands. Routed packets priority is determined by the DSCP field with the default translations. Bridged packets priority is determined by the PCP field, if exist, otherwise it is set to 0. Since both options have only priorities 0-7, higher priorities mapping are being ignored. Signed-off-by:

Add the ability to offload PRIO qdisc by using ndo_setup_tc. There are three commands for PRIO offloading: * TC_PRIO_REPLACE: handles set and tune * TC_PRIO_DESTROY: handles qdisc destroy * TC_PRIO_STATS: updates the qdiscs counters (given as reference) Like RED qdisc, the indication of whether PRIO is being offloaded is being set and updated as part of the dump function. It is so because the driver could decide to offload or not based on the qdisc parent, which could change without notifying the qdisc. Signed-off-by:

Add rdpm definition - router DSCP to priority mapping register. This register will be utilized later to align the default mapping between packet DSCP and switch-priority to the kernel's mapping between packet priority and skb priority. This is the first non-bit indexed register where the entries are arranged in descending order, i.e., entry at offset 0 matches configuration for dscp[63]. As a result, the item's step is converted into a signed variable to support descending arrays [where step would be negative]. Signed-off-by:

Since commit eb789980 ("mlxsw: spectrum_router: Populate adjacency entries according to weights") the driver includes support for non-equal-cost multipath, but IPv4 nexthops were the only user. Now that the kernel supports weighted IPv6 nexthops, we can extend the driver to support it as well. This is done by assigning each nexthop its configured weight, so that it will be populated accordingly in the device's adjacency table. The `weight` parameter is also taken into account when comparing nexthop groups in order not to consolidate non-identical groups. Signed-off-by:

This update makes it so that we report the actual number of Tx queues via real_num_tx_queues but are still restricted to RSS on only the first pool by setting num_tc equal to 1. Doing this locks us into only having the ability to setup XPS on the queues in that pool, and only those queues should be used for transmitting anything other than macvlan traffic. Signed-off-by:

This change makes it so that instead of bringing rings up/down for various we just update the netdev pointer for the Rx ring and set or clear the MAC filter for the interface. By doing it this way we can avoid a number of races and issues in the code as things were getting messy with the macvlan clean-up racing with the interface clean-up to bring the rings down on shutdown. With this change we opt to leave the rings owned by the PF interface for both Tx and Rx and just direct the packets once they are received to the macvlan netdev. Signed-off-by:

We should not be stopping/starting the upper devices Tx queues when handling a macvlan offload. Instead we should be stopping and starting traffic on our own queues. In order to prevent us from doing this I am updating the code so that we no longer change the queue configuration on the upper device, nor do we update the queue_index on our own device. Instead we can just use the queue index for our local device and not update the netdev in the case of the transmit rings. Signed-off-by:

We shouldn't be recording the Rx queue on macvlan offloaded frames since the macvlan is normally brought up as a single queue device, and it will trigger warnings for RPS if we have recorded queue IDs larger than the "real_num_rx_queues" value recorded for the device. Instead we should be recording the macvlan statistics since we are bypassing the normal macvlan statistics that would have been generated by the receive path. Signed-off-by:

The code throughout ixgbe was assuming that dev->num_tc was populated and configured with the driver, when in fact this can be configured via mqprio without any hardware coordination other than restricting us to the real number of Tx queues we advertise. Instead of handling things this way we need to keep a local copy of the number of TCs in use so that we don't accidentally pull in the TC configuration from mqprio when it is configured in software mode.

We might as well configure the limit to default to 1 pool always for the interface. This accounts for the fact that the PF counts as 1 pool if SR-IOV is enabled, and in general we are always running in 1 pool mode when RSS or DCB is enabled as well, though we don't need to actually evaluate any of the VMDq features in those cases.

The macvlan driver itself will validate the MAC address that is configured for a given interface. There is no need for us to verify it again.
