Subject: [PATCH net-next v2 9/9] bnxt_en: Add stored FW version info to devlink info_get cb.
Date: Mon, 12 Oct 2020 05:10:54 -0400	[thread overview]
Message-ID: <1602493854-29283-10-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1602493854-29283-1-git-send-email-michael.chan@broadcom.com>

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

This patch adds FW versions stored in the flash to devlink info_get
callback.  Return the correct fw.psid running version using the
newly added bp->nvm_cfg_ver.

v2:
Ensure stored pkg_name string is NULL terminated when copied to
devlink.

Return directly from the last call to bnxt_dl_info_put().

If the FW call to get stored version fails for any reason, return
success immediately to devlink without the stored versions.
