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:

Add a list of switch ports within the switch fabric. This will help the lookup of a port inside the whole fabric, and it is the first step towards supporting multiple CPU ports, before deprecating the usage of the unique dst->cpu_dp pointer.

Heiner Kallweit says: ==================== The attempt to improve performance by changing the PCIe max read request size was added in the vendor driver more than 10 years back and copied to r8169 driver. In the vendor driver this has been removed long ago. Obviously it had no effect, also in my tests I didn't see any difference. Typically the max payload size is less than 512 bytes anyway, and the PCI core takes care that the maximum supported value is set. So let's remove fiddling with PCIe max read request size from r8169 too. This change allows to simplify the driver in the subsequent three patches of this series. ==================== Signed-off-by: -

Ido Schimmel says: ==================== Vadim says: This patch set extends the size of QSFP EEPROM for the cable types SSF-8436 and SFF-8636 from 256 bytes to 640 bytes. This allows ethtool to show correct information for these cable types (more details below). Patch #1 adds a macro that computes the EEPROM page number from the provided offset specified in the request. Patch #2 teaches the driver to access the information stored in the upper pages of the QSFP memory map. Details and examples: SFF-8436 specification defines pages 0, 1, 2 and 3. Page 0 contains lower memory page offsets (from 0x00 to 0x7f) and upper page offsets (from 0x80 to 0xfe). Upper pages 1, 2 and 3 are optional and can be empty. Page 1 is provided if upper page 0 byte 0xc3 bit 6 is set. Page 2 is provided if upper page 0 byte 0xc3 bit 7 is set. Page 3 is provided if lower page 0 byte 0x02 bit 2 is cleared. Offset 0xc3 for the upper page is provided as 0x43 = 0xc3 - 0x80. As a result of exposing 256 bytes only, ethtool shows wrong information for pages 1, 2 and 3. In the below hex dump from ethtool for a cable compliant to SFF-8636 specification, it can be seen that EEPROM of this device contains optical diagnostic page (lower page 0 byte 0x02 bit 2 is cleared), but it is not exposed, as the length defined for this type is 256 bytes. $ ethtool -m sfp42 hex on Offset Values ------ ------ 0x0000: 11 07 00 ff 00 ff 00 00 00 55 55 00 00 00 00 00 0x0010: 00 00 00 00 00 00 2a 90 00 00 82 ae 00 00 00 00 0x0020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0040: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0050: 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 0x0060: 00 00 ff 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0070: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0080: 11 8c 0c 80 00 00 00 00 00 00 00 05 ff 00 00 23 0x0090: 00 00 32 00 4d 65 6c 6c 61 6e 6f 78 20 20 20 20 0x00a0: 20 20 20 20 00 00 02 c9 4d 4d 41 31 42 30 30 2d 0x00b0: 53 53 31 20 20 20 20 20 41 32 42 68 0b b8 46 05 0x00c0: 02 07 f5 9e 4d 54 31 38 33 34 46 54 30 33 38 34 0x00d0: 36 20 20 20 31 38 30 37 30 33 00 00 0c 10 67 c2 0x00e0: 38 32 36 46 4d 41 32 32 36 49 30 31 31 35 20 20 0x00f0: 00 00 00 00 00 00 00 00 00 00 01 00 0e 00 00 00 After changing the length returned by get_module_info() callback from 256 bytes to 640 bytes, the upper pages 1, 2 and 3 are exposed by ethtool.

Extend the size of QSFP EEPROM for the cable types SSF8436 and SFF8636 from 256 to 640 bytes in order to expose all the EEPROM pages by ethtool. For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes of data for ethtool's get_module_eeprom() callback. This is because the driver uses the below defines to specify SFF module length in ethtool's get_module_info() callback: 'ETH_MODULE_SFF_8636_LEN' and 'ETH_MODULE_SFF_8436_LEN' (both are 256). As a result of exposing 256 bytes only, ethtool shows wrong "zero" info for pages 1, 2, 3. The patch changes the length returned by callback for get_module_info() to the values from the next defines: 'ETH_MODULE_SFF_8636_MAX_LEN' and 'ETH_MODULE_SFF_8436_MAX_LEN' (both are 640) to allow exposing of upper page 1, 2 and 3.
