The DPAA Ethernet driver is using the FMan MAC as the device for DMA mapping. This is not actually correct, as the real DMA device is the FMan port (the FMan Rx port for reception and the FMan Tx port for transmission). Changing the device used for DMA mapping to the Fman Rx and Tx port devices. Signed-off-by:

Igor Russkikh says: ==================== net: aquantia: PTP support for AQC devices This patchset introduces PTP feature support in Aquantia AQC atlantic driver. This implementation is a joined effort of aquantia developers: Egor is the main designer and driver/firmware architect on PTP, Sergey and Dmitry are included as co-developers. Dmitry also helped me in the overall patchset preparations. Feature was verified on AQC hardware with testptp tool, linuxptp, gptp and with Motu hardware unit. version3 updates: - Review comments applied: error handling, various fixes version2 updates: - Fixing issues from Andrew's review: replacing self with ptp var name, making ptp_clk_offset a field in the ptp instance. devm_kzalloc advice is actually non applicable, because ptp object gets created/destroyed on each network device close/open and it should not be linked with dev lifecycle. - Rearranging commit authorship, adding Egor as a ptp module main maintainer - Fixing kbuild 32bit division issues ==================== Acked-by:

Depending on FW configuration we can manage from 0 to 3 PINs for periodic output and from 0 to 1 ext ts PIN for getting TS for external event. Ext TS PIN functionality is implemented via periodic timestamps polling directly from PHY, because right now there is now way to receive the PIN trigger interrupt from phy. The polling interval is 15 milliseconds. Co-developed-by:

Ido Schimmel says: ==================== mlxsw: Update main pool computation and pool size limits Petr says: In Spectrum ASICs, the shared buffer is an area of memory where packets are kept until they can be transmitted. There are two resources associated with shared buffer size: cap_total_buffer_size and cap_guaranteed_shared_buffer. So far, mlxsw has been using the former as a limit when validating shared buffer pool size configuration. However, the total size also includes headrooms and reserved space, which really cannot be used for shared buffer pools. Patch #1 mends this and has mlxsw use the guaranteed size. To configure default pool sizes, mlxsw has historically hard-coded one or two smallish pools, and one "main" pool that took most of the shared buffer (that would be pool 0 on ingress and pool 4 on egress). During the development of Spectrum-2, it became clear that the shared buffer size keeps shrinking as bugs are identified and worked around. In order to prevent having to tweak the size of pools 0 and 4 to catch up with updates to values reported by the FW, patch #2 changes the way these pools are set. Instead of hard-coding a fixed value, the main pool now takes whatever is left from the guaranteed size after the smaller pool(s) are taken into account. ==================== Signed-off-by: -

There are two resources associated with shared buffer size: cap_total_buffer_size, and cap_guaranteed_shared_buffer. So far, mlxsw has been using the former as a limit to determine how large a pool size is allowed to be. However, the total size also includes headrooms and reserved space, which really cannot be used for shared buffer pools. Therefore convert mlxsw to use the latter resource as a limit. Adjust hard-coded pool sizes to be the guaranteed size minus 256000 bytes for CPU port pool. On Spectrum-1 that actually leads to an increase. A follow-up patch will have this size calculated automatically. Signed-off-by:

Tao Ren says: ==================== net: phy: support 1000Base-X auto-negotiation for BCM54616S This patch series aims at supporting auto negotiation when BCM54616S is running in 1000Base-X mode: without the patch series, BCM54616S PHY driver would report incorrect link speed in 1000Base-X mode. Patch #1 (of 3) modifies assignment to OR when dealing with dev_flags in phy_attach_direct function, so that dev_flags updated in BCM54616S PHY's probe callback won't be lost. Patch #2 (of 3) adds several genphy_c37_* functions to support clause 37 1000Base-X auto-negotiation, and these functions are called in BCM54616S PHY driver. Patch #3 (of 3) detects BCM54616S PHY's operation mode and calls according genphy_c37_* functions to configure auto-negotiation and parse link attributes (speed, duplex, and etc.) in 1000Base-X mode. ==================== Signed-off-by: -
Tao Ren authored
The BCM54616S PHY cannot work properly in RGMII->1000Base-X mode, mainly because genphy functions are designed for copper links, and 1000Base-X (clause 37) auto negotiation needs to be handled differently. This patch enables 1000Base-X support for BCM54616S by customizing 3 driver callbacks, and it's verified to be working on Facebook CMM BMC platform (RGMII->1000Base-KX): - probe: probe callback detects PHY's operation mode based on INTERF_SEL[1:0] pins and 1000X/100FX selection bit in SerDES 100-FX Control register. - config_aneg: calls genphy_c37_config_aneg when the PHY is running in 1000Base-X mode; otherwise, genphy_config_aneg will be called. - read_status: calls genphy_c37_read_status when the PHY is running in 1000Base-X mode; otherwise, genphy_read_status will be called. Note: BCM54616S PHY can also be configured in RGMII->100Base-FX mode, and 100Base-FX support is not available as of now. Signed-off-by:Tao Ren <taoren@fb.com> Acked-by:

Vivien Didelot says: ==================== The dsa_switch structure represents the physical switch device itself, and is allocated by the driver. The dsa_switch_tree and dsa_port structures represent the logical switch fabric (eventually composed of multiple switch devices) and its ports, and are allocated by the DSA core. This branch lists the logical ports directly in the fabric which simplifies the iteration over all ports when assigning the default CPU port or configuring the D in DSA in drivers like mv88e6xxx. This also removes the unique dst->cpu_dp pointer and is a first step towards supporting multiple CPU ports and dropping the DSA_MAX_PORTS limitation. Because the dsa_port structures are not tied to the dsa_switch structure anymore, we do not need to provide an helper for the drivers to allocate a switch structure. Like in many other subsystems, drivers can now embed their dsa_switch structure as they wish into their private structure. This will be particularly interesting for the Broadcom drivers which were currently limited by the dynamically allocated array of DSA ports. The series implements the list of dsa_port structures, makes use of it, then drops dst->cpu_dp and the dsa_switch_alloc helper. ==================== Signed-off-by: -

Now that ports are dynamically listed in the fabric, there is no need to provide a special helper to allocate the dsa_switch structure. This will give more flexibility to drivers to embed this structure as they wish in their private structure. Signed-off-by:

Like the dsa_switch_tree structures, the dsa_port structures will be allocated on switch registration. The SJA1105 driver is the only one accessing the dsa_port structure after the switch allocation and before the switch registration. For that reason, move switch registration prior to assigning the priv member of the dsa_port structures. Signed-off-by:
