Subject: [PATCH net-next 02/15] bnxt_en: Define macros for the various health register states.
Date: Mon, 25 Jan 2021 02:08:08 -0500	[thread overview]
Message-ID: <1611558501-11022-3-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1611558501-11022-1-git-send-email-michael.chan@broadcom.com>

Define macros to check for the various states in the lower 16 bits of
the health register.  Replace the C code that checks for these values
with the newly defined macros.
