Subject: [PRE-REVIEW PATCH 06/16] net: mvpp2: Prepare to use the new tasklet API
From: Romain Perier <romain.perier@...eris.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.
