2021-03-24net: stmmac: Add hardware supported cross-timestampTan Tee Min8-0/+189
Cross timestamping is supported on Integrated Ethernet Controller in Intel SoC such as EHL and TGL with Always Running Timer. The hardware cross-timestamp result is made available to applications through the PTP_SYS_OFFSET_PRECISE ioctl which calls stmmac_getcrosststamp(). Device time is stored in the MAC Auxiliary register. The 64-bit System time (ART timestamp) is stored in registers that are only addressable by using MDIO space.

2021-03-23net: ipa: avoid 64-bit modulusAlex Elder2-7/+13
It is possible for a 32 bit x86 build to use a 64 bit DMA address. There are two remaining spots where the IPA driver does a modulo operation to check alignment of a DMA address, and under certain conditions this can lead to a build error on i386 (at least). The alignment checks we're doing are for power-of-2 values, and this means the lower 32 bits of the DMA address can be used. This ensures both operands to the modulo operator are 32 bits wide.

2021-03-23net: ocelot: replay switchdev events when joining bridgeVladimir Oltean4-32/+110
The premise of this change is that the switchdev port attributes and objects offloaded by ocelot might have been missed when we are joining an already existing bridge port, such as a bonding interface. The patch pulls these switchdev attributes and objects from the bridge, on behalf of the 'bridge port' net device which might be either the ocelot switch interface, or the bonding upper interface. The ocelot_net.c belongs strictly to the switchdev ocelot driver, while ocelot.c is part of a library shared with the DSA felix driver. The ocelot_port_bridge_leave function (part of the common library) used to call ocelot_port_vlan_filtering(false), something which is not necessary for DSA, since the framework deals with that already there. So we move this function to ocelot_switchdev_unsync, which is specific to the switchdev driver. The code movement described above makes ocelot_port_bridge_leave no longer return an error code, so we change its type from int to void.

2021-03-23net: ocelot: call ocelot_netdevice_bridge_join when joining a bridged LAGVladimir Oltean1-25/+86
Similar to the DSA situation, ocelot supports LAG offload but treats this scenario improperly: ip link add br0 type bridge ip link add bond0 type bond ip link set bond0 master br0 ip link set swp0 master bond0 We do the same thing as we do there, which is to simulate a 'bridge join' on 'lag join', if we detect that the bonding upper has a bridge upper. Again, same as DSA, ocelot supports software fallback for LAG, and in that case, we should avoid calling ocelot_netdevice_changeupper.

2021-03-23brcmfmac: p2p: Fix recently introduced deadlock issueHans de Goede1-1/+1
Commit a05829a7222e ("cfg80211: avoid holding the RTNL when calling the driver") replaced the rtnl_lock parameter passed to various brcmf functions with just lock, because since that commit it is not just about the rtnl_lock but also about the wiphy_lock . During this search/replace the "if (!rtnl_locked)" check in brcmfmac/p2p.c was accidentally replaced with "if (locked)", dropping the inversion of the check. This causes the code to now call rtnl_lock() while already holding the lock, causing a deadlock. Add back the "!" to the if-condition to fix this.

It's possible for iwl_pcie_enqueue_hcmd() to be called with hard IRQs disabled (e.g. from LED core). We can't enable BHs in such a situation. Turn the unconditional BH-enable/BH-disable code into hardirq-disable/conditional-enable. This fixes the warning below.

2021-03-22dpaa2-switch: mark skbs with offload_fwd_markIoana Ciornei1-0/+3
If a switch port is under a bridge, the offload_fwd_mark should be setup before sending the skb towards the stack so that the bridge does not try to flood the packet on the other switch ports. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-03-22dpaa2-switch: add support for configuring per port unknown floodingIoana Ciornei2-3/+21
Add support for configuring per port unknown flooding by accepting both BR_FLOOD and BR_MCAST_FLOOD as offloadable bridge port flags. The DPAA2 switch does not support at the moment configuration of unknown multicast flooding independently of unknown unicast flooding, therefore check that both BR_FLOOD and BR_MCAST_FLOOD have the same state.

2021-03-22dpaa2-switch: add support for configuring per port broadcast floodingIoana Ciornei2-3/+31
The BR_BCAST_FLOOD bridge port flag is now accepted by the driver and a change in its state will determine a reconfiguration of the broadcast egress flooding list on the FDB associated with the port.

2021-03-22dpaa2-switch: add support for configuring learning state per portIoana Ciornei4-11/+121
Add support for configuring the learning state of a switch port. When the user requests the HW learning to be disabled, a fast-age procedure on that specific port is run so that previously learnt addresses do not linger. At device probe as well as on a bridge leave action, the ports are configured with HW learning disabled since they are basically a standalone port. At the same time, at bridge join we inherit the bridge port BR_LEARNING flag state and configure it on the switch port. There were already some MC firmware ABI functions for changing the learning state, but those were per FDB (bridging domain) and not per port so we need to adjust those to use the new MC fw command which is per port.

2021-03-22dpaa2-switch: refactor the egress flooding domain setupIoana Ciornei1-13/+25
Extract the code that determines the list of egress flood interfaces for a specific flood type into a new function - dpaa2_switch_fdb_get_flood_cfg(). This will help us to not duplicate code when the broadcast and unknown ucast/mcast flooding domains will be individually configurable.
