100GbE Intel Wired LAN Driver Updates 2020-03-21
Implement basic support for the devlink interface in the ice driver.
Additionally pave some necessary changes for adding a devlink region that
exposes the NVM contents.
This series first contains 5 patches for enabling and implementing full NVM
read access via the ETHTOOL_GEEPROM interface. This includes some cleanup of
endian-types, a new function for reading from the NVM and Shadow RAM as a flat
addressable space, a function to calculate the available flash size during
load, and a change to how some of the NVM version fields are stored in the
ice_nvm_info structure.
Following this is 3 patches for implementing devlink support. First, one patch
which implements the basic framework and introduces the ice_devlink.c file.
Second, a patch to implement basic .info_get support. Finally, a patch which
reads the device PBA identifier and reports it as the `board.id` value in the
.info_get response.

With MTU sized receive buffers it is not expected to have CQE_RX
with multiple receive buffer pointers. But since same physcial link
is shared by PF and it's VFs, the max receive packet configured
at link could be morethan MTU. Hence there is a chance of receiving
plts morethan MTU which then gets DMA'ed into multiple buffers
and notified in a single CQE_RX. This patch treats such pkts as errors
and frees up receive buffers pointers back to hardware.
Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid
HW length errors for the packets whose size > MTU, eg due to path MTU.

On OcteonTx2 silicon there two two types VFs, VFs that share the
physical link with their parent SR-IOV PF and the VFs which work
in pairs using internal HW loopback channels (LBK). Except for the
underlying Rx/Tx channel mapping from netdev functionality perspective
they are almost identical. This patch adds netdev driver support
for these VFs.
Unlike it's parent PF a VF cannot directly communicate with admin
function (AF) and it has to go through PF for the same. The mailbox
communication with AF works like 'VF <=> PF <=> AF'.
Also functionality wise VF and PF are identical, hence to avoid code
duplication PF driver's APIs are resued here for HW initialization,
packet handling etc etc ie almost everything. For VF driver to compile
as module exported few of the existing PF driver APIs.

Added 'sriov_configure' to enable/disable virtual functions (VFs).
Also added handling of mailbox messages from these VFs.
Admin function (AF) is the only one with all priviliges to configure
HW, alloc resources etc etc, PFs and it's VFs have to request AF
via mbox for all their needs. But unlike PFs, their VFs cannot
send a mbox request directly. A VF shares a mailbox region with
it's parent PF, so VF sends a mailbox msg to PF and then PF forwards
it to AF. Then AF after processing sends response to PF which it
again forwards to VF.
This patch adds support for this 'VF <=> PF <=> AF' mailbox
communication.

The devlink .info_get callback allows the driver to report detailed

this initial implementation:
"fw.mgmt" -> The version of the firmware that controls PHY, link, etc
"fw.mgmt.api" -> API version of interface exposed over the AdminQ
"fw.mgmt.build" -> Unique build id of the source for the management fw
"fw.undi" -> Version of the Option ROM containing the UEFI driver
"fw.psid.api" -> Version of the NVM image format.
"fw.bundle_id" -> Unique identifier for the combined flash image.
"fw.app.name" -> The name of the active DDP package.
"fw.app" -> The version of the active DDP package.
With this, devlink dev info can report at least as much information as
is reported by ETHTOOL_GDRVINFO.

Begin implementing support for the devlink interface with the ice
driver.
The pf structure is currently memory managed through devres, via
a devm_alloc. To mimic this behavior, after allocating the devlink
pointer, use devm_add_action to add a teardown action for releasing the
devlink memory on exit.
The ice hardware is a multi-function PCIe device. Thus, each physical
function will get its own devlink instance. This means that each
function will be treated independently, with its own parameters and
configuration. This is done because the ice driver loads a separate
instance for each function.
Due to this, the implementation does not enable devlink to manage
device-wide resources or configuration, as each physical function will
be treated independently. This is done for simplicity, as managing
a devlink instance across multiple driver instances would significantly
increase the complexity for minimal gain.

When reading from the NVM using a flat address, it is useful to know the
upper bound on the size of the flash contents. This value is not stored
within the NVM.
We can determine the size by performing a bisection between upper and
lower bounds. It is known that the size cannot exceed 16 MB (offset of
0xFFFFFF).
Use a while loop to bisect the upper and lower bounds by reading one
byte at a time. On a failed read, lower the maximum bound. On
a successful read, increase the lower bound.
Save this as the flash_size in the ice_nvm_info structure that contains
data related to the NVM.
The size will be used in a future patch for implementing full NVM read
via ethtool's GEEPROM command.
The maximum possible size for the flash is bounded by the size limit for
the NVM AdminQ commands. Add a new macro, ICE_AQC_NVM_MAX_OFFSET, which
can be used to represent this upper bound.

The NVM contents are read via firmware by using the ice_aq_read_nvm
function. This function has a couple of limits:
1) The AdminQ commands can only take buffers sized up to 4Kb. Thus, any
larger read must be split into multiple reads.
2) when reading from the Shadow RAM, reads must not cross sector
boundaries. The sectors are also 4Kb in size.
Implement the ice_read_flat_nvm function to read portions of the NVM by
flat offset. That is, to read using offsets from the start of the NVM
rather than from a specific module.
This function will be able to read both from the NVM and from the Shadow
RAM. For simplicity NVM reads will always be broken up to not cross 4Kb
page boundaries, even though this is not required unless reading from
the Shadow RAM.
Use this new function as the implementation of ice_read_sr_word_aq.
The ice_read_sr_buf_aq function is not modified here. This is because
a following change will remove the only caller of that function in favor
of directly using ice_read_flat_nvm. Thus, there is little benefit to
changing it now only to remove it momentarily. At the same time, the
ice_read_sr_aq function will also be removed.

Chelsio NICs have 3 filter regions, in following order of priority:
1. High Priority (HPFILTER) region (Highest Priority).
2. HASH region.
3. Normal FILTER region (Lowest Priority).
Currently, there's a 1-to-1 mapping between the prio value passed
by TC and the filter region index. However, it's possible to have
multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the
next available region.
So, rework and remove the 1-to-1 mapping. Instead, dynamically select
the region to insert the filter rule, as long as the new rule's prio
value doesn't conflict with existing rules across all the 3 regions.

Adds the support for Enterprise MAC IP version which is very similar to
XGMAC. It's so similar that we just need to check the device id and add
new speeds definitions and some minor callbacks.
