Subject: [PATCH net-next 1/2] r8169: improve handling CPCMD_MASK
Date: Sun, 26 Apr 2020 23:35:59 +0200	[thread overview]
Message-ID: <9520bbc8-da51-5420-9c7f-dada47e68972@gmail.com> (raw)
In-Reply-To: <e076bba2-e4dc-f8ce-d119-5b6735017727@gmail.com>

It's sufficient to do the masking once in probe() for clearing
unwanted bits that may have been set by the BIOS.
