Subject: [PATCH v2 net-next] net: phy: improve definition of __ETHTOOL_LINK_MODE_MASK_NBITS
Date: Fri, 22 Feb 2019 19:25:59 +0100 [thread overview]
Message-ID: <3ae0478b-810f-904e-e128-7e0a57c7255c@gmail.com> (raw)
The way to define __ETHTOOL_LINK_MODE_MASK_NBITS seems to be overly
complicated, go with a standard approach instead.
Whilst we're at it, move the comment to the right place.
v2:
- rebased
