bf051a3b86 i40e: use same number of queues as CPUs

A better method is to use the total number of CPUs in the system
to suggest the number of queue pairs, which aligns better with
the behavior of ixgbe, and also with the expectations of the
kernel XPS and other subsystems in the stack.

f551b4386c i40e: fix pf reset after offline test
When the ethtool testing starts it sets the I40E_TESTING state
bit, which blocks new netdev opens so that things don't get
confused, while the testing might be messing with register and
other things.  Unfortunately, that was keeping the PF resets
after the register test from working correctly because the netdev
would not get reopened.  This patch reorders the tests to put the
register test last as it is the only one that needs a reset, and
we wait to trigger the reset until after we clear the
I40E_TESTING bit.

f72848021d sfc: Allow filter removal only with exactly matching priority
Currently a higher priority client can remove a lower priority
client's filter with equal match-expression.  This might happen if (a)
the higher priority client has a double-free bug, or (b) another
client with sufficient priority replaced and then removed an equal
filter, allowing the low priority client to insert an equal filter.

In neither case does it actually make sense to carry out the removal;
we should say the filter doesn't exist, as the filter currently
present is not the one that the high-priority client is referring to.

7665d1abea sfc: Change priority and flags for automatic MAC filters
MAC filters inserted automatically by the driver, based on the device
address list (EF10) or no-match filters (Siena), should be overridable
at MANUAL or REQUIRED priority.  Currently they themselves have
REQUIRED priority and this requires some odd special-casing.

We also can't reliably tell whether such a MAC filter has or has
not been overridden.  We just remember that it is wanted by the
stack (RX_STACK flag).

Add another priority level, AUTO, between HINT and MANUAL, and
use this for the automatic filters while they have not been
overridden.  Remove the RX_STACK flag.  Add an RX_OVER_AUTO
flag which is set only when an AUTO filter has been overridden
(or was requested to be inserted while a higher-priority filter
existed).

9aecda95d0 sfc: Enable PTP clock and timestamping for all functions on EF10
The SFC9100 family has only one clock per controller, shared by all
functions.  Therefore only create a clock device under the primary
function, and make all other functions refer to the primary's clock
device.

Since PTP functionality is limited to port 0 and PF 0 on the earlier
SFN[56]322F boards, and we also set the primary flag for that
function, we can make the creation of a clock device conditional only
on this flag.

0bcf4a645f sfc: Associate primary and secondary functions of controller
The primary function of an EF10 controller will share its clock
device with other functions in the same domain (which we call
secondary functions).  To this end, we need to associate functions
on the same controller.

We do not control probe order, so allow primary and secondary
functions to appear in any order.  Maintain global lists of all
primary functions and of unassociated secondary functions,
and a list of secondary functions on each primary function.

Use the VPD serial number to tell whether functions are part of the
same controller.  VPD will not be readable by virtual functions, so
this may need to be revisited later.
