Author: davidcs Date: Tue Mar 6 23:12:32 2018 New Revision: 330555 URL: https://svnweb.freebsd.org/changeset/base/330555 Log: MFC r329855 1. Added support to offline a port if is error recovery on successful. 2. Sysctls to enable/disable driver_state_dump and error_recovery. 3. Sysctl to control the delay between hw/fw reinitialization and restarting the fastpath. 4. Stop periodic stats retrieval if interface has IFF_DRV_RUNNING flag off. 5. Print contents of PEG_HALT_STATUS1 and PEG_HALT_STATUS2 on heartbeat failure. 6. Speed up slowpath shutdown during error recovery. 7. link_state update using atomic_store. 8. Added timestamp information on driver state and minidump captures. 9. Added support for Slowpath event logging 10.Added additional failure injection types to simulate failures.
