libie: commonize adminq structure
Michal Swiatkowski says:
It is a prework to allow reusing some specific Intel code (eq. fwlog).
Move common *_aq_desc structure to libie header and changing
it in ice, ixgbe, i40e and iavf.
Only generic adminq commands can be easily moved to common header, as
rest is slightly different. Format remains the same. It will be better
to correctly move it when it will be needed to commonize other part of
the code.
Move *_aq_str() to new libie module (libie_adminq) and use it across
drivers. The functions are exactly the same in each driver. Some more
adminq helpers/functions can be moved to libie_adminq when needed.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
i40e: use libie_aq_str
iavf: use libie_aq_str
ice: use libie_aq_str
libie: add adminq helper for converting err to str
iavf: use libie adminq descriptors
i40e: use libie adminq descriptors
ixgbe: use libie adminq descriptors
ice, libie: move generic adminq descriptors to lib

The descriptor structure is the same in ice, ixgbe and i40e. Move it to
common libie header to use it across different driver.
Leave device specific adminq commands in separate folders. This lead to
a change that need to be done in filling/getting descriptor:
- previous: struct specific_desc *cmd;
cmd = &desc.params.specific_desc;
- now: struct specific_desc *cmd;
cmd = libie_aq_raw(&desc);
Do this changes across the driver to allow clean build. The casting only
have to be done in case of specific descriptors, for generic one union
can still be used.
Changes beside code moving:
- change ICE_ prefix to LIBIE_ prefix (ice_ and libie_ too)
- remove shift variables not otherwise needed (in libie_aq_flags)
- fill/get descriptor data based on desc.params.raw whenever the
descriptor isn't defined in libie
- move defines from the libie_aq_sth structure outside
- add libie_aq_raw helper and use it instead of explicit casting

The Get Tx Topology AQ command (opcode 0x0418) has different read flag
requirements depending on the hardware/firmware. For E810, E822, and E823
firmware the read flag must be set, and for newer hardware (E825 and E830)
it must not be set.
This results in failure to configure Tx topology and the following warning
message during probe:
DDP package does not support Tx scheduling layers switching feature -
please update to the latest DDP package and try again
The current implementation only handles E825-C but not E830. It is
confusing as we first check ice_is_e825c() and then set the flag in the set
case. Finally, we check ice_is_e825c() again and set the flag for all other
hardware in both the set and get case.
Instead, notice that we always need the read flag for set, but only need
the read flag for get on E810, E822, and E823 firmware. Fix the logic to
check the MAC type and set the read flag in get only on the older devices
which require it.

Remove unnecessary ice_is_e8xx() functions and PHY model. Instead, use
MAC type where applicable.
Don't check device type in ice_ptp_maybe_trigger_tx_interrupt(), because
in reality it depends on the ready bitmap, which only E810 does not
have.
Call ice_ptp_cfg_phy_interrupt() unconditionally, because all further
function calls check the MAC type anyway and this allows simpler code
in the future with addition of the new MAC types.
Reorder ICE_MAC_* cases in switches in ice_ptp* as in enum ice_mac_type.

An optional flag field has been added to the signature segment header.
The field contains two flags, a "valid" bit, and a "last segment" bit
that indicates whether the segment is the last segment that will be
sent to firmware.
If the flag field's valid bit is NOT set, then as was done before,
assume that this is the last segment being downloaded.
However, if the flag field's valid bit IS set, then use the last segment
flag to determine if this segment is the last segment to download.

There is a performance issue when the number of VSIs are not multiple
of 8. This is caused due to the max children limitation per node(8) in
9 layer topology. The BW credits are shared evenly among the children
by default. Assume one node has 8 children and the other has 1.
The parent of these nodes share the BW credit equally among them.
Apparently this causes a problem for the first node which has 8 children.
The 9th VM get more BW credits than the first 8 VMs.
Example:
1) With 8 VM's:
for x in 0 1 2 3 4 5 6 7;
do taskset -c ${x} netperf -P0 -H 172.68.169.125 & sleep .1 ; done
tx_queue_0_packets: 23283027
tx_queue_1_packets: 23292289
tx_queue_2_packets: 23276136
tx_queue_3_packets: 23279828
tx_queue_4_packets: 23279828
tx_queue_5_packets: 23279333
tx_queue_6_packets: 23277745
tx_queue_7_packets: 23279950
tx_queue_8_packets: 0
2) With 9 VM's:
for x in 0 1 2 3 4 5 6 7 8;
do taskset -c ${x} netperf -P0 -H 172.68.169.125 & sleep .1 ; done
tx_queue_0_packets: 24163396
tx_queue_1_packets: 24164623
tx_queue_2_packets: 24163188
tx_queue_3_packets: 24163701
tx_queue_4_packets: 24163683
tx_queue_5_packets: 24164668
tx_queue_6_packets: 23327200
tx_queue_7_packets: 24163853
tx_queue_8_packets: 91101417
So on average queue 8 statistics show that 3.7 times more packets were
send there than to the other queues.
The FW starting with version 3.20, has increased the max number of
children per node by reducing the number of layers from 9 to 5. Reflect
this on driver side.
