Subject: [PATCH] net: mvpp2: Prepare to use the new tasklet API
Date: Mon, 17 Aug 2020 08:58:05 +0000	[thread overview]
Message-ID: <20200817084614.24263-4-allen.cryptic@gmail.com> (raw)
In-Reply-To: <20200817084614.24263-1-allen.cryptic@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.
