The TimeCard exposes different resources, which may have their
own irqs. Space for the irqs is allocated through a MSI or MSI-X
interrupt vector. On some platforms, the interrupt allocation
fails.
Rather than making this fatal, just skip exposing those resources.
The main timecard functionality (that of a PTP clock) will work
without the additional resources.

8W burst length is supported by ar9 and newer SoCs.
The NAT benchmark results on xRX200 (Down/Up):

This drops the code setting bit 9 on egress frames on the

This bit was set on ingress frames for unknown reason,
and was set on egress frames as the format of ingress
and egress frames was believed to be the same. As that
assumption turned out to be false, and since this bit
seems to have zero effect on the behaviour of the switch
let's drop this bit entirely.

PF support get MAC address space assigned by firmware
This series add support PF to get unicast/multicast MAC address space
assigned by firmware for the HNS3 ethernet driver.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The new firmware supports to divides the whole multicast MAC address space
equally to functions of all PFs, and calculates the space size of each PF
according to its function number.
To support this feature, PF driver adds querying multicast MAC address
space size from firmware and limits used number according to space size.

Signed-off-by: David S. Miller <davem@davemloft.net>
Currently, there are two ways for PF to set the unicast MAC address space
size: specified by config parameters in firmware or set to default value.
That's mean if the config parameters in firmware is zero, driver will
divide the whole unicast MAC address space equally to 8 PFs. However, in
this case, the unicast MAC address space will be wasted a lot when the
hardware actually has less then 8 PFs. And in the other hand, if one PF has
much more VFs than other PFs, then each function of this PF will has much
less address space than other PFs.
In order to ameliorate the above two situations, introduce the third way
of unicast MAC address space assignment: firmware divides the whole unicast
MAC address space equally to functions of all PFs, and calculates the space
size of each PF according to its function number. PF queries the space size
by the querying device specification command when in initialization
process.
The third way assignment is lower priority than specified by config
parameters, only if the config parameters is zero can be used, and if
firmware does not support the third way assignment, then driver still
divides the whole unicast MAC address space equally to 8 PFs.

Jiri says:
This patchset includes patches that prepare the driver to support modular

PLLP register is introduced to get front panel port label which is no
longer equivalent to "module + 1" for modular systems, where the
numbering is per line card.
So far for all systems all front panel ports had same format and could
be split to the same number of subports. This is no longer true for
modular systems, where every line card can have different types of front
panel ports.
The PMTDB register is introduced to easily query FW for split
capabilities of particular front panel port. It is generic for use in
modular and non-modular systems.
