2022-07-19net/mlx5e: Add resiliency for PTP TX port timestampAya Levin5-2/+50
PTP TX port timestamp relies on receiving 2 CQEs for each outgoing packet (WQE). The regular CQE has a less accurate timestamp than the wire CQE. On link change, the wire CQE may get lost. Let the driver detect and restore the relation between the CQEs, and re-sync after timeout. Add resiliency for this as follows: add id (producer counter) into the WQE's metadata. This id will be received in the wire CQE (in wqe_counter field). On handling the wire CQE, if there is no match, replay the PTP application with the time-stamp from the regular CQE and restore the sync between the CQEs and their SKBs. This patch adds 2 ptp counters: 1) ptp_cq0_resync_event: number of times a mismatch was detected between the regular CQE and the wire CQE. 2) ptp_cq0_resync_cqe: total amount of missing wire CQEs.

Fix an issue when driver incorrectly detects state of recovery process and erroneously reinitializes interrupts, which results in a kernel error and call trace message. The issue was caused by a combination of two factors: 1. Assuming the EMP reset issued after completing firmware recovery means the whole recovery process is complete. 2. Erroneous reinitialization of interrupt vector after detecting the above mentioned EMP reset. Fixes (1) by changing how recovery state change is detected and (2) by adjusting the conditional expression to ensure using proper interrupt reinitialization method, depending on the situation.

2022-07-15net: stmmac: fix unbalanced ptp clock issue in suspend/resume flowBiao Huang2-10/+15
Current stmmac driver will prepare/enable ptp_ref clock in stmmac_init_tstamp_counter(). The stmmac_pltfr_noirq_suspend will disable it once in suspend flow. But in resume flow, stmmac_pltfr_noirq_resume --> stmmac_init_tstamp_counter stmmac_resume --> stmmac_hw_setup --> stmmac_init_ptp --> stmmac_init_tstamp_counter ptp_ref clock reference counter increases twice, which leads to unbalance ptp clock when resume back. Move ptp_ref clock prepare/enable out of stmmac_init_tstamp_counter to fix it.
