H A D | bnx2x_vfpf.c | bf23ffc8 Fri Aug 18 11:14:40 CDT 2023 Thinh Tran <thinhtr@linux.vnet.ibm.com> bnx2x: new flag for track HW resource allocation
While injecting PCIe errors to the upstream PCIe switch of a BCM57810 NIC, system hangs/crashes were observed.
After several calls to bnx2x_tx_timout() complete, bnx2x_nic_unload() is called to free up HW resources and bnx2x_napi_disable() is called to release NAPI objects. Later, when the EEH driver calls bnx2x_io_slot_reset() to complete the recovery process, bnx2x attempts to disable NAPI again by calling bnx2x_napi_disable() and freeing resources which have already been freed, resulting in a hang or crash.
Introduce a new flag to track the HW resource and NAPI allocation state, refactor duplicated code into a single function, check page pool allocation status before freeing, and reduces debug output when a TX timeout event occurs.
