Currently the hw action stats update is called from tcf_exts_hw_stats_update, when a tc filter is dumped, and from tcf_action_copy_stats, when a hw action is dumped. However, the tcf_action_copy_stats is also called from tcf_action_dump. As such, the hw action stats update cb is called 3 times for every tc flower filter dump. Move the tc action hw stats update from tcf_action_copy_stats to tcf_dump_walker to update the hw action stats when tc action is dumped. Signed-off-by:

All implementations of the remove callback return 0 unconditionally. So in dwc_eth_dwmac_remove() there is no error handling necessary. Simplify accordingly. This is a preparation for making struct platform_driver::remove return void, too. Signed-off-by:

The function returns zero unconditionally. Change it to return void instead which simplifies some callers as error handing becomes unnecessary. This also makes it more obvious that most platform remove callbacks always return zero. Signed-off-by:

Add replacement for phy_ethtool_get/set_eee() functions. Current phy_ethtool_get/set_eee() implementation is great and it is possible to make it even better: - this functionality is for devices implementing parts of IEEE 802.3 specification beyond Clause 22. The better place for this code is phy-c45.c - currently it is able to do read/write operations on PHYs with different abilities to not existing registers. It is better to use stored supported_eee abilities to avoid false read/write operations. - the eee_active detection will provide wrong results on not supported link modes. It is better to validate speed/duplex properties against supported EEE link modes. - it is able to support only limited amount of link modes. We have more EEE link modes... By refactoring this code I address most of this point except of the last one. Adding additional EEE link modes will need more work. Signed-off-by:

KSZ8563R, which has same PHYID as KSZ9477 family, will change "EEE control and capability 1" (Register 3.20) content depending on configuration of "EEE advertisement 1" (Register 7.60). Changes on the 7.60 will affect 3.20 register. So, instead of depending on register 3.20, driver should set supported_eee. Proper supported_eee configuration is needed to make use of generic PHY c45 set/get_eee functions provided by next patches. Signed-off-by:

Add generic function for EEE abilities defined by IEEE 802.3 specification. For now following registers are supported: - IEEE 802.3-2018 45.2.3.10 EEE control and capability 1 (Register 3.20) - IEEE 802.3cg-2019 45.2.1.186b 10BASE-T1L PMA status register (Register 1.2295) Since I was not able to find any flag signaling support of these registers, we should detect link mode abilities first and then based on these abilities doing EEE link modes detection. Results of EEE ability detection will be stored into new variable phydev->supported_eee. Signed-off-by:

Some of KSZ9477 family switches provides EEE support. To enable it, we just need to register set_mac_eee/set_mac_eee handlers and validate supported chip version and port. Currently supported chip variants are: KSZ8563, KSZ9477, KSZ9563, KSZ9567, KSZ9893, KSZ9896, KSZ9897. KSZ8563 supports EEE only with 100BaseTX/Full. Other chips support 100BaseTX/Full and 1000BaseTX/Full. Low Power Idle configuration is not supported and currently not documented in the datasheets. EEE PHY specific tunings are not documented in the switch datasheets, but can overlap with KSZ9131 specification. Signed-off-by:

The ionic device has on-board memory (CMB) that can be used for descriptors as a way to speed descriptor access for faster packet processing. It is rumored to improve latency and/or packets-per-second for some profiles of small packet traffic, although your mileage may vary. Signed-off-by:

Alex Elder says: ==================== net: ipa: determine GSI register offsets differently This series changes the way GSI register offset are specified, using the "reg" mechanism currently used for IPA registers. A follow-on series will extend this work so fields within GSI registers are also specified this way. The first patch rearranges the GSI register initialization code so it is similar to the way it's done for the IPA registers. The second identifies all the GSI registers in an enumerated type. The third introduces "gsi_reg-v3.1.c" and uses the "reg" code to define one GSI register offset. The second-to-last patch just adds "gsi_reg-v3.5.1.c", because that version introduces a new register not previously defined. All the rest just define the rest of the GSI register offsets using the "reg" mechanism. Note that, to have continued lines align with an open parenthesis, new files created in this series cause some checkpatch warnings. ==================== Signed-off-by: -

Add the remaining GSI register offset definitions. Use gsi_reg() rather than the corresponding GSI_*_OFFSET() macros to get the offsets for these registers, and get rid of the macros. Note that we are now defining information for the HW_PARAM_2 register, and that doesn't appear until IPA v3.5.1. Signed-off-by:

Continue populating with GSI register definitions, adding remaining registers whose offset depends on a channel ID. Use gsi_reg() and reg_n_offset() to determine offsets for those registers, and get rid of the corresponding GSI_CH_C_*_OFFSET() macros. Signed-off-by:

Alex Elder authored
Create a new register definition file in the "reg" subdirectory, and begin populating it with GSI register definitions based on IPA version. The GSI registers haven't changed much, so several IPA versions can share the same GSI register definitions. As with IPA registers, an array of pointers indexed by GSI register ID refers to these register definitions, and a new "regs" field in the GSI structure is initialized in gsi_reg_init() to refer to register information based on the IPA version (though for now there's only one). The new function gsi_reg() returns register information for a given GSI register, and the result can be used to look up that register's offset. This patch is meant only to put the infrastructure in place, so only eon register (CH_C_QOS) is defined for each version, and only the offset and stride are defined for that register. Use new function gsi_reg() to look up that register's information to get its offset, This makes the GSI_CH_C_QOS_OFFSET() unnecessary, so get rid of it. Signed-off-by:
