[RFC net-next 0/5] net: dsa: LAG support

[Florian Fainelli <f.fainelli@gmail.com>]

Hi all,

This patch series is sent as RFC since I have only been able to test LAG
with dsa-loop and not with real HW yet (that should be tomorrow). I also
looked at how the Marvell DSDT API is defined for adding ports to "trunk"
groups and the API proposed here should work there too. Can't speak about
QCA, Mediatek or KSZ switches though.

Few open questions that may need solving now or later:

- on Broadcom switches, we should allow enslaving a port as a LAG group
  member if its speed does not match that of the other members of the group

- not sure what to do with a switch fabric, naively, if adding two ports
  of two distinct switches as a LAG group, we may have to propagate that
  to "dsa" cross-chip interfaces as well

Thanks!
