Message-Id: <1533502318-22359-10-git-send-email-michael.chan@broadcom.com>
Date: Sun, 5 Aug 2018 16:51:54 -0400

Subject: [PATCH net-next 09/13] bnxt_en: Move firmware related flags to a new fw_cap field in struct bnxt.
The flags field is almost getting full. Move firmware capability flags
to a new fw_cap field to better organize these firmware flags.
