Message-Id: <1533502318-22359-9-git-send-email-michael.chan@broadcom.com>
Date: Sun, 5 Aug 2018 16:51:53 -0400
From: Michael Chan <michael.chan@...adcom.com>

Cc: netdev@...r.kernel.org, Michael Chan <michael.chan@...adocm.com>
Subject: [PATCH net-next 08/13] bnxt_en: Add BNXT_NEW_RM() macro.
The BNXT_FLAG_NEW_RM flag is checked a lot in the code to determine if
the new resource manager is in effect. Define a macro to perform
this check.
