[dpdk-dev] [PATCH 4/5] net/bnxt: check access denied error for HWRM commands

[Ajit Khaparde]

Firmware can restrict access to certain resources in the hardware
depending on various factors. In such cases when the PMD tries to
configure these resources the firmware will return
HWRM_ERR_CODE_RESOURCE_ACCESS_DENIED error. Parse this and return
the standard EACCES error to the applications.

Fixes: 804e746c7b73 ("net/bnxt: add hardware resource manager init code")
