2019-09-03ice: Only disable VLAN pruning for the VF when all VLANs are removedBrett Creeley
Currently if the VF adds a VLAN, VLAN pruning will be enabled for that VSI. Also, when a VLAN gets deleted it will disable VLAN pruning even if other VLAN(s) exists for the VF. Fix this by only disabling VLAN pruning on the VF VSI when removing the last VF (i.e. vf->num_vlan == 0).

2019-09-03ice: Remove enable DCB when SW LLDP is activatedMichal Swiatkowski
Remove code that enables DCB in initialization when SW LLDP is activated. DCB flag is set or reset before in ice_init_pf_dcb based on number of TCs. So there is not need to overwrite it. Setting DCB without checking number of TCs can cause communication problems with other cards. Host card sends packet with VLAN priority tag, but client card doesn't strip this tag and ping doesn't work.

2019-09-03ice: Report stats when VSI is downDave Ertman
There is currently a check in get_ndo_stats that returns before updating stats if the VSI is down or there are no Tx or Rx queues. This causes the netdev to report zero stats with the netdev is down.

2019-09-03ice: Always notify FW of VF resetMitch Williams
The call to ice_dis_vsi_txq() acts as the notification to the firmware that the VF is being reset. Because of this, we need to make this call every time we reset, regardless of whatever else we do to stop the Tx queues. Without this change, VF resets would fail to complete on interfaces that were up and running.

2019-09-03net/mlx5: Add devlink flow_steering_mode parameterMaor Gottlieb
Add new parameter (flow_steering_mode) to control the flow steering mode of the driver. Two modes are supported: 1. DMFS - Device managed flow steering 2. SMFS - Software/Driver managed flow steering. In the DMFS mode, the HW steering entities are created through the FW. In the SMFS mode this entities are created though the driver directly. The driver will use the devlink steering mode only if the steering domain supports it, for now SMFS will manages only the switchdev eswitch steering domain. User command examples: - Set SMFS flow steering mode:: $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime - Read device flow steering mode:: $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode pci/0000:06:00.0: name flow_steering_mode type driver-specific values: cmode runtime value smfs Signed-off-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2019-09-03net/mlx5: DR, ICM pool memory allocatorAlex Vesker
ICM device memory is used for writing steering rules (STEs) to the NIC. An ICM memory pool allocator was implemented to manage the required memory. The pool consists of buckets, a bucket per chunk size. Once a bucket is empty we will cut a row of memory from the latest allocated MR, if the MR size is not sufficient we will allocate a new MR. HW design requires that chunks memory address should be aligned to the chunk size, this is the reason for managing the MR with row size that insures memory alignment. Current design is greedy in memory but provides quick allocation times in steady state.

2019-09-03selftests/bpf: fix endianness issues in test_sysctlIlya Leoshkevich
A lot of test_sysctl sub-tests fail due to handling strings as a bunch of immediate values in a little-endian-specific manner. Fix by wrapping all immediates in bpf_ntohl and the new bpf_be64_to_cpu. fixup_sysctl_value() dynamically writes an immediate, and thus should be endianness-aware.

2019-09-03brcmfmac: get chip's default RAM info during PCIe setupRafał Miłecki
Getting RAM info just once per driver's lifetime (during chip recognition) is not enough as it may get adjusted later (depending on the used firmware). Subsequent inits may load different firmwares so a full RAM recognition is required on every PCIe setup. This is especially important since implementing hardware reset on a firmware crash. Moreover calling brcmf_chip_get_raminfo() makes sure that RAM core is up. It's important as having BCMA_CORE_SYS_MEM down on BCM4366 was resulting in firmware failing to initialize and following error: [ 65.657546] brcmfmac 0000:01:00.0: brcmf_pcie_download_fw_nvram: Invalid shared RAM address 0x04000001 This change makes brcmf_chip_get_raminfo() call during chip recognition redundant for PCIe devices but SDIO and USB still need it and it's a very small overhead anyway.

According to documentation IEEE80211_TX_STAT_AMPDU_NO_BACK is suppose to be used when we do not recive BA (BlockAck). However on rt2x00 we use it when remote station fail to decode one or more subframes within AMPDU (some bits are not set in BlockAck bitmap). Setting the flag result in sent of BAR (BlockAck Request) frame and this might result of abuse of BA session, since remote station can sent BA with incorrect sequence numbers after receiving BAR. This problem is visible especially when connecting two rt2800 devices. Previously I observed some performance benefits when using the flag when connecting with iwlwifi devices. But currently possibly due to reacent changes in rt2x00 removing the flag has no effect on those test cases. So remove the IEEE80211_TX_STAT_AMPDU_NO_BACK.
