2021-10-25net: qed_ptp: fix check of true !rc expressionJean Sacren
Remove the check of !rc in (!rc && !params.b_granted) since it is always true. We should also use constant 0 for return. Signed-off-by: Jean Sacren <sakiwit@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-07-06net: qed: cleanup global structs declarationsAlexander Lobakin
Fix several sparse warnings by moving structs declarations into the corresponding header files: drivers/net/ethernet/qlogic/qed/qed_dcbx.c:2402:32: warning: symbol 'qed_dcbnl_ops_pass' was not declared. Should it be static? drivers/net/ethernet/qlogic/qed/qed_ll2.c:2754:26: warning: symbol 'qed_ll2_ops_pass' was not declared. Should it be static? drivers/net/ethernet/qlogic/qed/qed_ptp.c:449:30: warning: symbol 'qed_ptp_ops_pass' was not declared. Should it be static? drivers/net/ethernet/qlogic/qed/qed_sriov.c:5265:29: warning: symbol 'qed_iov_ops_pass' was not declared. Should it be static? (some of them were declared twice in different header files) Also make qed_hw_err_type_descr[] const while at it.

2020-02-05qed: Fix timestamping issue for L2 unicast ptp packets.Sudarsana Reddy Kalluru
commit cedeac9df4b8 ("qed: Add support for Timestamping the unicast PTP packets.") handles the timestamping of L4 ptp packets only. This patch adds driver changes to detect/timestamp both L2/L4 unicast PTP packets. Fixes: cedeac9df4b8 ("qed: Add support for Timestamping the unicast PTP packets.")

2017-05-02qed*: Fix issues in the ptp filter config implementation.sudarsana.kalluru@cavium.com
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.

2017-04-27qed: Add support for PTP resource locking.sudarsana.kalluru@cavium.com
The patch adds support for per-port resource lock in favour of PTP. PTP module acquires/releases the MFW resource lock while enabling/ disabling the PTP on the interface. The PF instance which has the ownership of this resource lock will get the exclusive access to the PTP clock functionality on the port.
