Add an helper function to read the next valid VLAN entry for a given port. It is used in the VID to FID conversion function to retrieve the forwarding database assigned to a given VLAN port. Finally update the FDB getnext operation to iterate on the next valid port VLAN when the end of the current database is reached.

Implement the port_pvid_get and vlan_getnext driver functions required to dump VLAN entries from the hardware, with the VTU Get Next operation. Some functions and structure will be shared with STU operations, since their table format are similar (e.g. STU data entries are accessible with the same registers as VTU entries, except with an offset of 2).

Add new functions in DSA drivers to access hardware VLAN entries through SWITCHDEV_OBJ_PORT_VLAN objects: - port_pvid_get() and vlan_getnext() to dump a VLAN - port_vlan_del() to exclude a port from a VLAN - port_pvid_set() and port_vlan_add() to join a port to a VLAN The DSA infrastructure will ensure that each VLAN of the given range does not already belong to another bridge. If it does, it will fallback to software VLAN and won't program the hardware. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Like the ipv4 patch with a similar title, this adds a sysctl to allow the user to change routing behavior based on whether or not the interface associated with the nexthop was an up or down link. The default setting preserves the current behavior, but anyone that enables it will notice that nexthops on down interfaces will no longer be selected: net.ipv6.conf.all.ignore_routes_with_linkdown = 0 net.ipv6.conf.default.ignore_routes_with_linkdown = 0 net.ipv6.conf.lo.ignore_routes_with_linkdown = 0 ... When the above sysctls are set, not only will link status be reported to userspace, but an indication that a nexthop is dead and will not be used is also reported. 1000::/8 via 7000::2 dev p7p1 metric 1024 dead linkdown pref medium 1000::/8 via 8000::2 dev p8p1 metric 1024 pref medium 7000::/8 dev p7p1 proto kernel metric 256 dead linkdown pref medium 8000::/8 dev p8p1 proto kernel metric 256 pref medium 9000::/8 via 8000::2 dev p8p1 metric 2048 pref medium 9000::/8 via 7000::2 dev p7p1 metric 1024 dead linkdown pref medium fe80::/64 dev p7p1 proto kernel metric 256 dead linkdown pref medium fe80::/64 dev p8p1 proto kernel metric 256 pref medium This also adds devconf support and notification when sysctl values change. v2: drop use of rt6i_nhflags since it is not needed right now Signed-off-by: Andy Gospodarek <gospo@cumulusnetworks.com> Signed-off-by: Dinesh Dutt <ddutt@cumulusnetworks.com> Signed-off-by: David S.

Add support to track current link status of ipv6 nexthops to match recent changes that added support for ipv4 nexthops. This takes a simple approach to track linkdown status for next-hops and simply checks the dev for the dst entry and sets proper flags that to be used in the netlink message. v2: drop use of rt6i_nhflags since it is not needed right now Signed-off-by: Andy Gospodarek <gospo@cumulusnetworks.com> Signed-off-by: Dinesh Dutt <ddutt@cumulusnetworks.com> Signed-off-by: David S.

Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops. The driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is no event when the neigh is removed from the device (such as when the device goes admin down). This patches hooks ndo_neigh_destroy so the driver can know when a neigh is removed from the device. In response, the driver will purge the neigh entry from its internal tbl. I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if this ndo is vestigial or if there are out-of-tree users. In any case, it does what I need here. An alternative design would be to generate NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to NUD_NONE so driver knows neigh entry is dead.

Jeremy Linton says: ==================== Enable smsc911x for use with ACPI This set of patches enables the front Ethernet port on the ARM Juno development platform when used with an ACPI enabled kernel. These patches covert the of_property* calls in the driver to the DT/ACPI agnostic device_property* calls, and add the arm hardware id to the acpi_match_table. To support the above changes I copied a couple routines from of_net into the properties.c file, and modified them to be ACPI/DT agnostic. I'm not 100% sure this is the correct location for these functions. But I think they are required to avoid having a dozen different implementations scattered across assorted Ethernet adapters that are being enabled to use ACPI properties. ==================== Signed-off-by: David S.

OF has some helper functions for parsing MAC and PHY settings. In cases where the platform is providing this information rather than the device itself, there needs to be similar functions for ACPI. These functions are slightly modified versions of the ones in of_net which can use information provided via DT or ACPI. Signed-off-by: Jeremy Linton <jeremy.linton@arm.com> Signed-off-by: David S.

If TLP was unable to send a probe, it extended the RTO to now + icsk_rto. But extending the RTO makes little sense if no TLP probe went out. With this commit, instead of extending the RTO we re-arm it relative to the transmit time of the write queue head.

As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and C0_RX_PEND interrupt outputs provide a single transmit interrupt that combines transmit channel interrupts TXPEND[7:0] and a single receive interrupt that combines receive channel interrupts RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are connected to the ARM Cortex-A8 interrupt controller (INTC) rather than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even though CPSW interrupt is cleared by writing appropriate values to EOI register the interrupt is not cleared in IRQ controller. So interrupt is still pending and CPU is struck in ISR, the workaround is to disable the interrupts in ARM irq controller.

They were cleanups, but they break dosemu by changing the signal return behavior (and removing 'fs' and 'gs' from the sigcontext struct - while not actually changing any behavior - causes build problems).

When a system has multiple ethernet devices and during DHCP request (for using NFS), the system waits only for HZ/2 which is 500mS before switching to another interface for DHCP. There are some routers (Ex: Trendnet routers) which responds to DHCP request at about 560mS. When the system has only one ethernet interface there is no issue as the timeout is 2S and the dev xid doesn't changes and only retries. But when the system has multiple Ethernet like DRA74x with CPSW in dual EMAC mode, the DHCP response is dropped as the dev xid changes while shifting to the next device. So changing inter device timeout to HZ (which is 1S). Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
