2018-10-15dpaa2-eth: remove unused priv parameterIoana Ciornei1-6/+4
The priv parameter is never used in the build_linear_skb and drain_channel function. Remove it from the function definitions. Signed-off-by: Ioana Ciornei <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-15dpaa2-eth: fix uninitialized variable warningsIoana Ciornei1-3/+3
All 3 cases of possible uninitialized variables are false positives since they are used only as output parameters. Nonetheless, fix the warnings. Signed-off-by: Ioana Ciornei <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-15dpaa2-eth: make dpaa2_eth_set_dist_key staticIoana Ciornei1-2/+2
The dpaa2_eth_set_dist_key function is only used in a single file. Make it static. Signed-off-by: Ioana Ciornei <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-15dpaa2-eth: Fix Kconfig dependenciesIoana Radulescu1-1/+0
Both ARCH_LAYERSCAPE and COMPILE_TEST dependencies are already implied through the FSL_MC_BUS dep, so there's no need to state it explicitly. Also, the fsl-mc bus depends on COMPILE_TEST only for some architectures (arm, arm64, ppc, x86), so it's not correct to claim build support unconditionally.

2018-10-08dpaa2-eth: Don't account Tx confirmation frames on NAPI pollIoana Ciocoi Radulescu2-26/+47
Until now, both Rx and Tx confirmation frames handled during NAPI poll were counted toward the NAPI budget. However, Tx confirmations are lighter to process than Rx frames, which can skew the amount of work actually done inside one NAPI cycle. Update the code to only count Rx frames toward the NAPI budget and set a separate threshold on how many Tx conf frames can be processed in one poll cycle. The NAPI poll routine stops when either the budget is consumed by Rx frames or when Tx confirmation frames reach this threshold.

2018-10-08net: dpaa2: fix and improve dpaa2-ptp driverYangbo Lu1-16/+9
This patch is to fix and improve dpaa2-ptp driver in some places. - Fixed the return for some functions. - Replaced kzalloc with devm_kzalloc. - Removed dev_set_drvdata(dev, NULL). - Made ptp_dpaa2_caps const.

2018-10-08net: dpaa2: remove unused code for dprtcYangbo Lu3-723/+0
This patch is to removed unused code for dprtc. This code will be re-added along with more features of dpaa2-ptp added. Signed-off-by: Yangbo Lu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-08net: dpaa2: rename rtc as ptp in dpaa2-ptp driverYangbo Lu1-15/+15
In dpaa2-ptp driver, it's odd to use rtc in names of some functions and structures except these dprtc APIs. This patch is to use ptp instead of rtc in names. Signed-off-by: Yangbo Lu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-08net: dpaa2: fix dependency of config FSL_DPAA2_ETHYangbo Lu1-1/+1
The NETDEVICES dependency and ETHERNET dependency hadn't been required since dpaa2-eth was moved out of staging. Also allowed COMPILE_TEST for dpaa2-eth. Signed-off-by: Yangbo Lu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-08net: dpaa2: move DPAA2 PTP driver out of staging/Yangbo Lu7-2/+1266
This patch is to move DPAA2 PTP driver out of staging/ since the dpaa2-eth had been moved out. Signed-off-by: Yangbo Lu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-02dpaa2-eth: Add ethtool support for flow classificationIoana Radulescu6-0/+549
Add support for inserting and deleting Rx flow classification rules through ethtool. We support classification based on some header fields for flow-types ether, ip4, tcp4, udp4 and sctp4. Rx queues are core affine, so the action argument effectively selects on which cpu the matching frame will be processed. Discarding the frame is also supported.

2018-10-02dpaa2-eth: Configure Rx flow classification keyIoana Radulescu5-16/+148
For firmware versions that support it, configure an Rx flow classification key at probe time. Hardware expects all rules in the classification table to share the same key. So we setup a key containing all supported fields at driver init and when a user adds classification rules through ethtool, we will just mask out the unused header fields. Since the key composition process is the same for flow classification and hashing, reuse existing code where possible. Signed-off-by: Ioana Radulescu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-02dpaa2-eth: Rename structureIoana Radulescu2-7/+7
Since the array of supported header fields will be used for Rx flow classification as well, rename it from "hash_fields" to the more inclusive "dist_fields". Signed-off-by: Ioana Radulescu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-02dpaa2-eth: Use new API for Rx flow hashingIoana Radulescu5-19/+142
The Management Complex (MC) firmware initially allowed the configuration of a single key to be used both for Rx flow hashing and flow classification. This prevented us from supporting Rx flow classification through ethtool. Starting with version 10.7.0, the Management Complex(MC) offers a new set of APIs for separate configuration of Rx hashing and classification keys. Update the Rx flow hashing support to use the new API, if available. Signed-off-by: Ioana Radulescu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-09-24dpaa2-eth: Make Rx flow hash key configurableIoana Ciocoi Radulescu3-5/+41
Until now, the Rx flow hash key was a 5-tuple (IP src, IP dst, IP nextproto, L4 src port, L4 dst port) fixed value that we configured at probe. Add support for configuring this hash key at runtime. We support all standard header fields configurable through ethtool, but cannot differentiate between flow types, so the same hash key is applied regardless of protocol. We also don't support the discard option. Signed-off-by: Ioana Radulescu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-09-01dpaa2-eth: Move DPAA2 Ethernet driver from staging to drivers/netIoana Radulescu9-0/+6937
The DPAA2 Ethernet driver supports Freescale/NXP SoCs with DPAA2 (DataPath Acceleration Architecture v2). The driver manages network objects discovered on the fsl-mc bus. Signed-off-by: Ioana Radulescu <[email protected]> Signed-off-by: David S. Miller <[email protected]>
