2019-10-15net: ethernet: broadcom: have drivers select DIMLIB as neededRandy Dunlap
NET_VENDOR_BROADCOM is intended to control a kconfig menu only. It should not have anything to do with code generation. As such, it should not select DIMLIB for all drivers under NET_VENDOR_BROADCOM. Instead each driver that needs DIMLIB should select it (being the symbols SYSTEMPORT, BNXT, and BCMGENET).

Individual descriptors on LRO TCP session should be checked for CRC errors. It was discovered that HW recalculates L4 checksums on LRO session and does not break it up on bad L4 csum. Thus, driver should aggregate HW LRO L4 statuses from all individual buffers of LRO session and drop packet if one of the buffers has bad L4 checksum.

2019-10-14PCI: Add PCI_STD_NUM_BARS for the number of standard BARsDenis Efremov
Code that iterates over all standard PCI BARs typically uses PCI_STD_RESOURCE_END. However, that requires the unusual test "i <= PCI_STD_RESOURCE_END" rather than something the typical "i < PCI_STD_NUM_BARS". Add a definition for PCI_STD_NUM_BARS and change loops to use the more idiomatic C style to help avoid fencepost errors.

2019-10-13net/ibmvnic: Fix EOI when running in XIVE mode.Cédric Le Goater
pSeries machines on POWER9 processors can run with the XICS (legacy) interrupt mode or with the XIVE exploitation interrupt mode. These interrupt contollers have different interfaces for interrupt management : XICS uses hcalls and XIVE loads and stores on a page. H_EOI being a XICS interface the enable_scrq_irq() routine can fail when the machine runs in XIVE mode. Fix that by calling the EOI handler of the interrupt chip.

Accordingly to Synopsys documentation [1] and [2], when bit PPSEN0 in register MAC_PPS_CONTROL is set it selects the functionality command in the same register, otherwise selects the functionality control. Command functionality is required to either enable (command 0x2) and disable (command 0x5) the flexible PPS output, but the bit PPSEN0 is currently set only for enabling. Set the bit PPSEN0 to properly disable flexible PPS output. Tested on STM32MP15x, based on dwmac 4.10a.

2019-10-08net: hns3: support tx-scatter-gather-fraglist featureYunsheng Lin
The hardware supports up to 8 TX BD for non-tso skb and up to 63 TX BD for TSO skb. Currently, the hns3 driver supports RX skb with fraglist when HW GRO is enabled, when the stack forwards a RX skb with fraglist, the stack need to linearize the skb before sending to other interface without TX fraglist support. This patch adds support for TX fraglist. The performance increases from 1 GByte to 1.5 GByte for one iperf TCP stream during forwarding test after this patch. BTW, the minimum BD number of ring should be updated to 72 for supporting TX fraglist.

2019-10-06net: stmmac: Implement L3/L4 Filters in GMAC4+Jose Abreu
GMAC4+ cores support Layer 3 and Layer 4 filtering. Add the corresponding callbacks in these cores. Signed-off-by: Jose Abreu <joabreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-06net: stmmac: selftests: Add tests for VLAN Perfect FilteringJose Abreu
Add two new tests for VLAN Perfect Filtering. While at it, increase a little bit the tests strings lenght so that we can have more descriptive test names. Signed-off-by: Jose Abreu <joabreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-06net: stmmac: Fallback to VLAN Perfect filtering if HASH is not availableJose Abreu
If VLAN Hash Filtering is not available we can fallback to perfect filtering instead. Let's implement this in XGMAC and GMAC cores and let the user use this filter. VLAN VID=0 always passes filter so we check if more than 2 VLANs are created and return proper error code if so because perfect filtering only supports 1 VID at a time.

2019-10-06net: stmmac: selftests: Fix L2 Hash Filter testJose Abreu
With the current MAC addresses hard-coded in the test we can get some false positives as we use the Hash Filtering method. Let's change the MAC addresses in the tests to be unique when hashed.

2019-10-06net: stmmac: gmac4+: Not all Unicast addresses may be availableJose Abreu
Some setups may not have all Unicast addresses filters available. Check the number of available filters before trying to setup it. Fixes: 477286b53f55 ("stmmac: add GMAC4 core support") Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-06net: stmmac: selftests: Check if filtering is available before runningJose Abreu
We need to check if the number of available Hash Filters is enough to run the test, otherwise we will get false failures. Fixes: 091810dbded9 ("net: stmmac: Introduce selftests support") Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-06mlxsw: minimal: Add validation for FW versionVadim Pasternak
Add validation for FW version in order to prevent driver initialization in case FW version is older than expected. FW version validation is necessary, because use of a new field 'num_of_modules' in MGPIR register is not backward compatible. FW 'minor' and 'subminor' versions are expected to be greater than or equal to 2000 and 1886, respectively.

2019-10-06mlxsw: core: Push minor/subminor fw version check into helperVadim Pasternak
Add new API for FW "minor" and "subminor" version validation for sharing it between "spectrum" and "minimal" drivers. Use it in "spectrum" driver.

2019-10-06mlxsw: thermal: Provide optimization for QSFP modules number detectionVadim Pasternak
Use new field "num_of_modules" of MGPIR register for "thermal" interface in order to get the number of modules supported by system directly from the system configuration, instead of getting it from port to module mapping info.
