Subject: [PRE-REVIEW PATCH 06/16] net: mvpp2: Prepare to use the new tasklet API
Date: Sun, 29 Sep 2019 18:30:18 +0200 [thread overview]
Message-ID: <20190929163028.9665-7-romain.perier@gmail.com> (raw)
In-Reply-To: <20190929163028.9665-1-romain.perier@gmail.com>
From: Romain Perier <romain.perier@viveris.fr>
The future tasklet API will no longer allow to pass an arbitrary
"unsigned long" data parameter. The tasklet data structure will need to
be embedded into a data structure that will be retrieved from the tasklet
handler. Currently, there are no ways to retrieve the "struct mvpp2_port
*" from a given "struct mvpp2_port_pcpu *". This commit adds a new field
to get the address of the main port for each pcpu context.
