2019-03-07nfp: fix simple vNIC mailbox lengthDirk van der Merwe1-1/+1
The simple vNIC mailbox length should be 12 decimal and not 0x12. Using a decimal also makes it clear this is a length value and not another field within the simple mailbox defines. Found by code inspection, there are no known firmware configurations where this would cause issues.

It's not wrong because the callbacks (get_timestamp and config_sub_second_increment respectively) are the ones that initialize the variables. While it's unlikely that the callbacks are ever going to disappear and make that condition false, we can easily avoid this warning by zero initialize the variables.

2019-03-07enic: fix build warning without CONFIG_CPUMASK_OFFSTACKArnd Bergmann1-3/+3
The enic driver relies on the CONFIG_CPUMASK_OFFSTACK feature to dynamically allocate a struct member, but this is normally intended for local variables. Building with clang, I get a warning for a few locations that check the address of the cpumask_var_t: drivers/net/ethernet/cisco/enic/enic_main.c:122:22: error: address of array 'enic->msix[i].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] As far as I can tell, the code is still correct, as the truth value of the pointer is what we need in this configuration.

2019-03-07ravb: Decrease TxFIFO depth of Q3 and Q2 to oneMasaru Nagai1-1/+1
Hardware has the CBS (Credit Based Shaper) which affects only Q3 and Q2. When updating the CBS settings, even if the driver does so after waiting for Tx DMA finished, there is a possibility that frame data still remains in TxFIFO. To avoid this, decrease TxFIFO depth of Q3 and Q2 to one. This patch has been exercised this using netperf TCP_MAERTS, TCP_STREAM and UDP_STREAM tests run on an Ebisu board.

Full tx blocking (as opposed to CCA blocking) should only happen if there is a continuous non-802.11 signal above the energy detect threshold. Unfortunately the ED/CCA counter can't detect that, as it also counts 802.11 signals as busy. Similar to the vendor code, implement a learning mode that waits until the AGC gain has already been adjusted to the lowest value (due to false CCA events), and the number of false CCA events still remains high, and the blocking threshold is exceeded for more than 5 seconds.

2019-03-05mm: replace all open encodings for NUMA_NO_NODEAnshuman Khandual1-2/+3
Patch series "Replace all open encodings for NUMA_NO_NODE", v3. All these places for replacement were found by running the following grep patterns on the entire kernel code. Please let me know if this might have missed some instances. This might also have replaced some false positives. I will appreciate suggestions, inputs and review. 1. git grep "nid == -1" 2. git grep "node == -1" 3. git grep "nid = -1" 4. git grep "node = -1" This patch (of 2): At present there are multiple places where invalid node number is encoded as -1. Even though implicitly understood it is always better to have macros in there. Replace these open encodings for an invalid node number with the global macro NUMA_NO_NODE. This helps remove NUMA related assumptions like 'invalid node' from various places redirecting them to a common definition.

When team is used in loadbalance mode a BPF filter can be used to provide a hash which will determine the Tx port. When the netdev is later unregistered the filter is not freed which results in memory leaks [1]. Fix by freeing the program and the corresponding filter when unregistering the netdev.

2019-03-04net: dsa: mv88e6xxx: support in-band signalling on SGMII ports with external ↵Heiner Kallweit4-14/+52
PHYs If an external PHY is connected via SGMII and uses in-band signalling then the auto-negotiated values aren't propagated to the port, resulting in a broken link. See discussion in [0]. This patch adds this propagation. We need to call mv88e6xxx_port_setup_mac(), therefore export it from chip.c. Successfully tested on a ZII DTU with 88E6390 switch and an Aquantia AQCS109 PHY connected via SGMII to port 9.

The minimal driver is chip independent and uses I2C bus for chip access. Its purpose is to support chassis management on systems equipped with Mellanox switch ASICs. For example from BMC (Board Management Controller) device. Expose a dummy netdev for each front panel port and implement basic ethtool operations to obtain QSFP/SFP module info through ethtool.
