2019-10-01net: stmmac: xgmac: Detect Hash Table size dinamicallyJose Abreu2-0/+2
Since commit b8ef7020d6e5 ("net: stmmac: add support for hash table size 128/256 in dwmac4"), we can detect the Hash Table dinamically. Let's implement this feature in XGMAC cores and fix possible setups that don't support the maximum size for Hash Table. Signed-off-by: Jose Abreu <[email protected]> Signed-off-by: David S.

2019-09-27mlxsw: spectrum: Clear VLAN filters during port initializationIdo Schimmel1-0/+9
When a port is created, its VLAN filters are not cleared by the firmware. This causes tagged packets to be later dropped by the ingress STP filters, which default to DISCARD state. The above did not matter much until commit b5ce611fd96e ("mlxsw: spectrum: Add devlink-trap support") where we exposed the drop reason to users. Without this patch, the drop reason users will see is not consistent. If a port is enslaved to a VLAN-aware bridge and a packet with an invalid VLAN tries to ingress the bridge, it will be dropped due to ingress STP filter. If the VLAN is later enabled and then disabled, the packet will be dropped by the ingress VLAN filter despite the above being a seemingly NOP operation. Fix this by clearing all the VLAN filters during port initialization. Adjust the test accordingly.

2019-09-25net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can runJuliet Kim2-68/+157
Commit a5681e20b541 ("net/ibmnvic: Fix deadlock problem in reset") made the change to hold the RTNL lock during a reset to avoid deadlock but linkwatch_event is fired during the reset and needs the RTNL lock. That keeps linkwatch_event process from proceeding until the reset is complete. The reset process cannot tolerate the linkwatch_event processing after reset completes, so release the RTNL lock during the process to allow a chance for linkwatch_event to run during reset. This does not guarantee that the linkwatch_event will be processed as soon as link state changes, but is an improvement over the current code where linkwatch_event processing is always delayed, which prevents transmissions on the device from being deactivated leading transmit watchdog timer to time-out. Release the RTNL lock before link state change and re-acquire after the link state change to allow linkwatch_event to grab the RTNL lock and run during the reset.

2019-09-24net/mlx5e: Fix matching on tunnel addresses typeDmytro Linkin1-36/+53
In mlx5 parse_tunnel_attr() function dispatch on encap IP address type is performed by directly checking flow_rule_match_key() on FLOW_DISSECTOR_KEY_ENC_IPV4_ADDRS, and then on FLOW_DISSECTOR_KEY_ENC_IPV6_ADDRS. However, since those are stored in union, first check is always true if any type of encap address is set, which leads to IPv6 tunnel encap address being parsed as IPv4 by mlx5. Determine correct IP address type by checking control key first and if it set, take address type from match.key->addr_type.

2019-09-19ibmvnic: Warn unknown speed message only when carrier is presentMurilo Fossa Vicentini1-3/+4
With commit 0655f9943df2 ("net/ibmvnic: Update carrier state after link state change") we are now able to detect when the carrier is properly present in the device, so only report an unexpected unknown speed when it is properly detected. Unknown speed is expected to be seen by the device in case the backing device has no link detected.
