Subject: [PATCH net-next 02/11] bnxt_en: Refactor the HWRM_VER_GET firmware calls
From: Edwin Peer <edwin.peer@...adcom.com>
Refactor the code so that __bnxt_hwrm_ver_get() does not call
bnxt_hwrm_do_send_msg() directly. The new APIs will not expose this
internal call. Add a new bnxt_hwrm_poll() to poll the HWRM_VER_GET
firmware call silently. The other bnxt_hwrm_ver_get() function will
send the HWRM_VER_GET message directly with error logs enabled.
