Subject: [PATCH net 4/6] bnxt_en: Suppress HWRM errors for HWRM_NVM_GET_VARIABLE command
Date: Fri, 16 Aug 2019 18:33:35 -0400
Message-ID: <1565994817-6328-5-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1565994817-6328-1-git-send-email-michael.chan@broadcom.com>

From: Vasundhara Volam <vasundhara-v.volam@broadcom.com>

For newly added NVM parameters, older firmware may not have the support.
Suppress the error message to avoid the unncessary error message which is
triggered when devlink calls the driver during initialization.

Fixes: 782a624d00fa ("bnxt_en: Add bnxt_en initial params table and register it.")
