[4/5] net/bnxt: check access denied error for HWRM commands
Checks
Commit Message
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")
