Subject: [PATCH net-next 0/2] net: stmmac: Fix MSI vector leak, make stmmac
 NUMA aware

Hi all,

This are some fallouts of a quick stmmac "review", while trying to
understand some issues that we have around the IRQ spreading implemented
by stmmac.

The root cause turned out to be something more generic, so not limited
to stmmac. I will try to prepare a discussion starting point later. This
is more a RT specific problem, so I have to bring in more people.

Meanwhile I think it's worth to share some first findings.
