When a default VLAN is added to the VF, the VF driver needs to reset to pick up the default VLAN ID. We can use the same tx timeout reset logic to do that, without the debug output.

The PF can setup a default VLAN for a VF. The default VLAN tag is automatically inserted and stripped without the knowledge of the stack running on the VF. The VF driver needs to know that default VLAN is enabled as VLAN acceleration on the RX side is no longer supported. Call netdev_update_features() to fix up the VLAN features as necessary. Also, VLAN strip mode must be enabled to strip out the default VLAN tag. Only allow VF default VLAN to be set if the firmware spec is >= 1.2.1.

alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workqueue mlxsw_wq is used for FDB notif. processing with workitems that are involved in normal device operation && because it's a network device which can be depended upon during memory reclaim. Workitems &trans->timeout_dw and &mlxsw_sp->fdb_notify.dw, map to mlxsw_sp_fdb_notify_work (processes FDB notifications from the underlying device and resolves the netdev to which the entry points to and notifies the bridge using the switchdev notifier) and mlxsw_emad_trans_timeout_work (provides async EMAD register access) respectively. They require forward progress under memory pressure and hence, WQ_MEM_RECLAIM has been set. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary here.

alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem viz (&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status) is involved in a brief poll routine for checking transmit queue status and is an intergral part of normal device operation. WQ_MEM_RECLAIM has been set to guarantee forward progress under memory pressure, which is a requirement here. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty.

mlx4 RSS is limited to spread incoming packets to a power of two number of queues. An uniformly distibuted traffic would be split on queues 0 to N-1, N being a power of two, each queue having a 1/N weight. If number of RX queues is not a power of two, upper RX queues do not receive traffic. ethtool -x is lying, because it pretends some queues have higher weight.

Blue flame is a latency enhancement feature that allows the driver to write the packet data directly to the NIC's registers thus making the read of the packet data from host memory redundant. We maintain a quota for the blue flame which is reloaded whenever we identify that the hardware is processing send requests and processes them fast enough so by the time we post the next send request it was able to process all the pending ones. This indicates that the hardware is capable of processing more blue flame requests efficiently. The blue flame quota is decremented whenever we send using blue flame. The current code erroneously clears the budget if we did not use blue flame for the current post send operation and we fix it here.

When a port is created following a split / unsplit we need to map it to the correct module and lane, enable it and then continue to initialize its various parameters such as MTU and VLAN filters. Under certain conditions, such as trying to split ports at the bottom row of the front panel by four, we get firmware errors. After evaluating this with the firmware team it was decided to alter the split / unsplit flow, so that first all the affected ports are mapped, then enabled and finally each is initialized separately. Fix the split / unsplit flow by first mapping and enabling all the affected ports. Newer firmware versions will support both flows.

Currently, we do not distribute queue resources to enable RSS for VFs in multi-channel/partition configurations. Fix this by having each PF(SRIOV capable) calculate it's share of the 15 RSS Policy Tables available per port before provisioning resources for all the VFs. This proportional share calculation is done based on division of the PF's MAX VFs with the Total MAX VFs on that port. It also needs to learn about the no: of NIC PFs on the port and subtract that from the 15 RSS Policy Tables on the port.

Skyhawk does support wake-up from ACPI shutdown state - S5, provided the platform supports it (like Auxiliary power source etc). The changes listed below are done to fix this. 1) There's no need to defer the HW configuration of WOL to be_suspend(). Remove this in be_suspend() and move it to be_set_wol() ethtool function so it is configured directly in the context of ethtool. This automatically takes care of the shutdown case. 2) The driver incorrectly uses WOL_CAP field in the FW response to get_acpi_wol_cap() command, to determine if WOL is enabled. Instead the driver must rely on the macaddr field in the response to infer WOL state. 3) In be_get_config() during init, if we find that WOL is enabled in FW, call pci_enable_wake() to enable pmcsr.pme_en bit. This is needed to support persistent WOL configuration provided by the FW in some platforms. 4) Remove code in be_set_wol() that writes to PCICFG_PM_CONTROL_OFFSET to set pme_en bit; pci_enable_wake() sets that.

This logic breaks when there are less number of TX-queues than RSS-queues. This patch fixes this problem by using the max-TXQs available in the PF-pool in the calculations.
