Message-Id: <20180830182238.16361-3-ar@cs.msu.ru> Date: Thu, 30 Aug 2018 21:22:38 +0300 From: Arseny Maslennikov <ar@...msu.ru> To: linux-rdma@...r.kernel.org Cc: Arseny Maslennikov <ar@...msu.ru>, Doug Ledford <dledford@...hat.com>, Jason Gunthorpe <jgg@...pe.ca>, netdev@...r.kernel.org Subject: [PATCH v2 2/2] Documentation/ABI: document /sys/class/net/*/dev_port The sysfs field was introduced 4 years ago along with fixes to various drivers that erroneously used `dev_id' for that purpose, but it was not properly documented anywhere. See commit v3.14-rc3-739-g3f85944fe207.
