For debugging issues in the field, we need to track some of the resources destroyed in the past. This is primarily required for tracking certain QPs that encountered errors, leading to application exits. A framework has been implemented to save this information and retrieve it during coredump collection. The Broadcom bnxt L2 driver supports collecting driver dumps using the ethtool -w option. This feature now also supports collecting coredump information from the bnxt_re auxiliary driver. Two new callbacks have been implemented to exchange dump information supported by the auxbus bnxt_re driver. The bnxt_re driver caches certain hardware information before resources are destroyed in the HW. Additionally, some resource information from the host is necessary for gathering meaningful debug information. Both types of information are cached by the driver for a finite (1024 for now) number of resources. Please review and apply.
