Read new NIC capability field which represnts 16 MSBs of the max flow counters number supported (max_flow_counter_31_16). Backward compatibility with older firmware is preserved, the modified driver reads max_flow_counter_31_16 as 0 from the older firmware and uses up to 64K counters. Changed flow counter id from 16 bits to 32 bits. Backward compatibility with older firmware is preserved as we kept the 16 LSBs of the counter id in place and added 16 MSBs from reserved field.

When mlx5_ib registers itself to mlx5_core as an interface, it will call mlx5_add_device which will call mlx5_ib interface add callback, in case the latter successfully returns, only then mlx5_core will add it to the interface list and async events will be forwarded to mlx5_ib. Between mlx5_ib interface add callback and mlx5_core adding the mlx5_ib interface to its devices list, arriving mlx5_core events can be missed by the new mlx5_ib registering interface. In other words: thread 1: mlx5_ib: mlx5_register_interface(dev) thread 1: mlx5_core: mlx5_add_device(dev) thread 1: mlx5_core: ctx = dev->add => (mlx5_ib)->mlx5_ib_add thread 2: mlx5_core_event: **new event arrives, forward to dev_list thread 1: mlx5_core: add_ctx_to_dev_list(ctx) /* previous event was missed by the new interface.*/ It is ok to miss events before dev->add (mlx5_ib)->mlx5_ib_add_device but not after. We fix this race by accumulating the events that come between the ib_register_device (inside mlx5_add_device->(dev->add)) till the adding to the list completes and fire them to the new registering interface after that.

Multi-Physical Function Switch (MPFs) is required for when multi-PF configuration is enabled to allow passing user configured unicast MAC addresses to the requesting PF. Before this patch eswitch.c used to manage the HW MPFS l2 table, E-Switch always (regardless of sriov) enabled vport(0) (NIC PF) vport's contexts update on unicast mac address list changes, to populate the PF's MPFS L2 table accordingly. In downstream patch we would like to allow compiling the driver without E-Switch functionalities, for that we move MPFS l2 table logic out of eswitch.c into its own file, and provide Kconfig flag (MLX5_MPFS) to allow compiling out MPFS for those who don't want Multi-PF support. NIC PF netdevice will now directly update MPFS l2 table via the new MPFS API. VF netdevice has no access to MPFS L2 table, so E-Switch will remain responsible of updating its MPFS l2 table on behalf of its VFs. Due to this change we also don't require enabling vport(0) (PF vport) unicast mac changes events anymore, for when SRIOV is not enabled. Which means E-Switch is now activated only on SRIOV activation, and not required otherwise.

Before the GMAC on the Anarion chip can be used, the PHY interface selection must be configured with the DWMAC block in reset. This layer covers a block containing only two registers. Although it is possible to model this as a reset controller and use the "resets" property of stmmac, it's much more intuitive to include this in the glue layer instead.

When using Broadcom Systemport device in 32bit Platform, ifconfig can only report up to 4G tx,rx status, which will be wrapped to 0 when the number of incoming or outgoing packets exceeds 4G, only taking around 2 hours in busy network environment (such as streaming).

Add support for SFP hotpluggable modules via sfp-bus and phylink. This supports both copper and optical SFP modules, which require different Serdes modes in order to properly negotiate the link. Optical SFP modules typically require the Serdes link to be talking 1000BaseX mode - this is the gigabit ethernet mode defined by the 802.3 standard. Copper SFP modules typically integrate a PHY in the module to convert from Serdes to copper, and the PHY will be configured by the vendor to either present a 1000BaseX Serdes link (for fixed 1000BaseT) or a SGMII Serdes link. However, this is vendor defined, so we instead detect the PHY, switch the link to SGMII mode, and use traditional PHY based negotiation.

The link between the ethernet MAC and its PHY has become more complex as the interface evolves. This is especially true with serdes links, where the part of the PHY is effectively integrated into the MAC. Serdes links can be connected to a variety of devices, including SFF modules soldered down onto the board with the MAC, a SFP cage with a hotpluggable SFP module which may contain a PHY or directly modulate the serdes signals onto optical media with or without a PHY, or even a classical PHY connection. Moreover, the negotiation information on serdes links comes in two varieties - SGMII mode, where the PHY provides its speed/duplex/flow control information to the MAC, and 1000base-X mode where both ends exchange their abilities and each resolve the link capabilities. This means we need a more flexible means to support these arrangements, particularly with the hotpluggable nature of SFP, where the PHY can be attached or detached after the network device has been brought up. Ethtool information can come from multiple sources: - we may have a PHY operating in either SGMII or 1000base-X mode, in which case we take ethtool/mii data directly from the PHY. - we may have a optical SFP module without a PHY, with the MAC operating in 1000base-X mode - the ethtool/mii data needs to come from the MAC. - we may have a copper SFP module with a PHY whic can't be accessed, which means we need to take ethtool/mii data from the MAC. Phylink aims to solve this by providing an intermediary between the MAC and PHY, providing a safe way for PHYs to be hotplugged, and allowing a SFP driver to reconfigure the serdes connection. Phylink also takes over support of fixed link connections, where the speed/duplex/flow control are fixed, but link status may be controlled by a GPIO signal. By avoiding the fixed-phy implementation, phylink can provide a faster response to link events: fixed-phy has to wait for phylib to operate its state machine, which can take several seconds. In comparison, phylink takes milliseconds.
