2019-06-28net: sched: refactor reinsert actionJohn Hurley
The TC_ACT_REINSERT return type was added as an in-kernel only option to allow a packet ingress or egress redirect. This is used to avoid unnecessary skb clones in situations where they are not required. If a TC hook returns this code then the packet is 'reinserted' and no skb consume is carried out as no clone took place. This return type is only used in act_mirred. Rather than have the reinsert called from the main datapath, call it directly in act_mirred. Instead of returning TC_ACT_REINSERT, change the type to the new TC_ACT_CONSUMED which tells the caller that the packet has been stolen by another process and that no consume call is required. Moving all redirect calls to the act_mirred code is in preparation for tracking recursion created by act_mirred.

2019-06-28ipv4: enable route flushing in network namespacesChristian Brauner
Tools such as vpnc try to flush routes when run inside network namespaces by writing 1 into /proc/sys/net/ipv4/route/flush. This currently does not work because flush is not enabled in non-initial network namespaces. Since routes are per network namespace it is safe to enable /proc/sys/net/ipv4/route/flush in there.

Since some MSI-X interrupt's status may be cleared by hardware, so when the driver receives the interrupt, reading HCLGE_VECTOR0_PF_OTHER_INT_STS_REG register will get an empty unknown interrupt. For this case, the irq handler should enable vector0 interrupt.

2019-06-28net: dsa: sja1105: Check for PHY mode mismatches with what PHYLINK reportsVladimir Oltean
PHYLINK being designed with PHYs in mind that can change MII protocol, for correct operation it is necessary to ensure that the PHY interface mode stays the same (otherwise clear the supported bit mask, as required). Because this is just a hypothetical situation for now, we don't bother to check whether we could actually support the new PHY interface mode. Actually we could modify the xMII table, reset the switch and send an updated static configuration, but adding that would just be dead code.

2019-06-28net: dsa: sja1105: Don't check state->link in phylink_mac_configVladimir Oltean
It has been pointed out that PHYLINK can call mac_config only to update the phy_interface_type and without knowing what the AN results are. Experimentally, when this was observed to happen, state->link was also unset, and therefore was used as a proxy to ignore this call. However it is also suggested that state->link is undefined for this callback and should not be relied upon. So let the previously-dead codepath for SPEED_UNKNOWN be called, and update the comment to make sure the MAC's behavior is sane.

Regmap provides read-modify-write function to update bitfields in registers. Replace ad-hoc read-modify-write with regmap_update_bits() where applicable.

2019-06-27net: dsa: microchip: Replace ksz9477_wait_alu_sta_ready polling with regmapMarek Vasut
Regmap provides polling function to poll for bits in a register. This function is another reimplementation of polling for bit being clear in a register. Replace this with regmap polling function. Moreover, inline the function parameters, as the function is never called with any other parameter values than this one.
