This patch-set adds support for some features of the Marvell switch
chips that can be used to handle packet storms.
The rationale for this was a setup that requires the ability to receive
traffic from one port, while a packet storm is occuring on another port
(via an external switch with a deliberate loop). This is needed to
ensure vital data delivery from a specific port, while mitigating any
loops or DoS that a user may introduce on another port (can't guarantee
sensible users).
[patch 1/7] configures auto negotiation for CPU ports connected with
phys to enable pause frame propogation.
[patch 2/7] allows setting of port's default output queue priority for
any ingressing packets on that port.
[patch 3/7] dt-bindings for patch 2.
[patch 4/7] allows setting of a port's queue scheduling so that it can
prioritise egress of traffic routed from high priority ports.
[patch 5/7] dt-bindings for patch 4.
[patch 6/7] allows ports to rate limit their egress. This can be used to
stop the host CPU from becoming swamped by packet delivery and exhasting
descriptors.
[patch 7/7] dt-bindings for patch 6.
