2018-11-27qede: Simplify the usage of qede-flags.Sudarsana Reddy Kalluru1-3/+3
The values represented by qede->flags is being used in mixed ways: 1. As 'value' at some places e.g., QEDE_FLAGS_IS_VF usage 2. As bit-mask(value) at some places e.g., QEDE_FLAGS_PTP_TX_IN_PRORGESS usage. This implementation pose problems in future when we want to add more flag values e.g., overlap of the values, overflow of 64-bit storage. Updated the implementation to go with approach (2) for qede->flags.

2018-07-02qede: Adverstise software timestamp caps when PHC is not available.Sudarsana Reddy Kalluru1-2/+8
When ptp clock is not available for a PF (e.g., higher PFs in NPAR mode), get-tsinfo() callback should return the software timestamp capabilities instead of returning the error.

2017-05-21net: ethernet: update drivers to handle HWTSTAMP_FILTER_NTP_ALLMiroslav Lichvar1-0/+1
Include HWTSTAMP_FILTER_NTP_ALL in net_hwtstamp_validate() as a valid filter and update drivers which can timestamp all packets, or which explicitly list unsupported filters instead of using a default case, to handle the filter.

2017-05-02qed*: Fix issues in the ptp filter config implementation.sudarsana.kalluru@cavium.com1-6/+28
PTP hardware filter configuration performed by the driver for a given user requested config is not correct for some of the PTP modes. Following changes are needed for PTP config-filter implementation. 1. NIG_REG_TX_PTP_EN register - Bits 0/1/2 respectively enables TimeSync/"V1 frame format support"/"V2 frame format support" on the TX side. Set the associated bits based on the user request. 2. ptp4l application fails to operate in Peer Delay mode. Following changes are needed to fix this, a. Driver should enable (set to 0) DA #1-related bits for IPv4, IPv6 and MAC destination addresses in these registers: NIG_REG_TX_LLH_PTP_RULE_MASK NIG_REG_LLH_PTP_RULE_MASK b. NIG_REG_LLH_PTP_PARAM_MASK/NIG_REG_TX_LLH_PTP_PARAM_MASK should be set to 0x0 in all modes.

2017-05-02qede: Fix concurrency issue in PTP Tx path processing.sudarsana.kalluru@cavium.com1-0/+4
PTP Tx timestamping data structures are not protected against the concurrent access in the Tx paths. Protecting the same using atomic bit locks.

2017-04-27qede: Add support for PTP resource locking.sudarsana.kalluru@cavium.com1-80/+70
The patch adds necessary changes to the driver to use qed resource locking functionality. Currently the ptp initialization is spread between driver probe/open implementations, associated APIs are qede_ptp_register_phc()/qede_ptp_start(). Clubbed this functionality into single API qed_ptp_enable() to simplify the usage of qed resource locking implementation. The new API will be invoked in the probe path. Similarly the ptp clean-up code is moved to qede_ptp_disable() which gets invoked in the driver unload path.
