====================
bnxt_en: Implement new driver APIs to send FW messages
The current driver APIs to send messages to the firmware allow only one
outstanding message in flight. There is only one buffer for the firmware
response for each firmware channel. To send a firmware message, all
callers must take a mutex and it is released after the firmware response
has been read. This scheme does not allow multiple firmware messages
in flight. Firmware may take a long time to respond to some messages
(e.g. NVRAM related ones) and this causes the mutex to be held for
a long time, blocking other callers.
This patchset intoduces the new driver APIs to address the above
shortcomings. The new APIs are compatible with new and old firmware.
But the new deferred firmware response mechanism will require newer
firmware in order to allow multiple outstanding firmware commands.
All callers are updated to use the new APIs.

or more concurrent commands after receiving deferred response events.
For uniformity and completeness, use the same pending list for
collecting completions for commands that respond via a completion ring.
These commands are only used for freeing rings and for IRQ test and
we only support one such command in flight.
Note deferred responses are also only supported on the main channel.

using hwrm_req_init().
2. If we don't need to read the firmware response, the hwrm_send_message()
call is replaced with hwrm_req_send().
3. If we need to read the firmware response, the mutex lock is replaced
by hwrm_req_hold() to hold the response. When the response is read, the
mutex unlock is replaced by hwrm_req_drop().
If additional DMA buffers are needed for firmware response data, the
hwrm_req_dma_slice() is used instead of calling dma_alloc_coherent().
Some minor refactoring is also done while doing these conversions.

Slices are a mechanism for suballocating DMA mapped regions from the

bound to the request and will be automatically unmapped when the

bnxt_en: introduce new firmware message API based on DMA pools
This change constitutes a major step towards supporting multiple
firmware commands in flight by maintaining a separate response buffer
for the duration of each request. These firmware commands are also
known as Hardware Resource Manager (HWRM) commands. Using separate
response buffers requires an API change in order for callers to be
able to free the buffer when done.
It is impossible to keep the existing APIs unchanged. The existing
usage for a simple HWRM message request such as the following:
struct input req = {0};
bnxt_hwrm_cmd_hdr_init(bp, &req, REQ_TYPE, -1, -1);
rc = hwrm_send_message(bp, &req, sizeof(req), HWRM_CMD_TIMEOUT);
if (rc)
/* error */
changes to:
struct input *req;
rc = hwrm_req_init(bp, req, REQ_TYPE);
if (rc)
/* error */
rc = hwrm_req_send(bp, req); /* consumes req */
if (rc)
/* error */
The key changes are:
1. The req is no longer allocated on the stack.
2. The caller must call hwrm_req_init() to allocate a req buffer and
check for a valid buffer.
3. The req buffer is automatically released when hwrm_req_send() returns.
4. If the caller wants to check the firmware response, the caller must
call hwrm_req_hold() to take ownership of the response buffer and
release it afterwards using hwrm_req_drop(). The caller is no longer
required to explicitly hold the hwrm_cmd_lock mutex to read the
response.
5. Because the firmware commands and responses all have different sizes,
some safeguards are added to the code.
This patch maintains legacy API compatibiltiy, implementing the old
API in terms of the new. The follow-on patches will convert all
callers to use the new APIs.

Commit
369956ae5720 ("rtlwifi: rtl8192de: Remove redundant variable
initializations") removed the initialization of place but it appears
that this removal was in the wrong function.
_rtl92c_phy_get_rightchnlplace() returns place's value at the end of the
function so now if the if statement is false, place never gets
initialized. Add that initialization back to address the warning.
place's initialization is not necessary in
rtl92d_get_rightchnlplace_for_iqk() as place is only used within the if
statement so it can be removed, which is likely what was intended in the
first place.

ipv6: add IFLA_INET6_RA_MTU to expose mtu value
The kernel provides a "/proc/sys/net/ipv6/conf/<iface>/mtu"
file, which can temporarily record the mtu value of the last
received RA message when the RA mtu value is lower than the
interface mtu, but this proc has following limitations:
(1) when the interface mtu (/sys/class/net/<iface>/mtu) is
updeated, mtu6 (/proc/sys/net/ipv6/conf/<iface>/mtu) will
be updated to the value of interface mtu;
(2) mtu6 (/proc/sys/net/ipv6/conf/<iface>/mtu) only affect
ipv6 connection, and not affect ipv4.
Therefore, when the mtu option is carried in the RA message,
there will be a problem that the user sometimes cannot obtain
RA mtu value correctly by reading mtu6.
After this patch set, if a RA message carries the mtu option,
you can send a netlink msg which nlmsg_type is RTM_GETLINK,
and then by parsing the attribute of IFLA_INET6_RA_MTU to
get the mtu value carried in the RA message received on the
inet6 device. In addition, you can also get a link notification
when ra_mtu is updated so it doesn't have to poll.
In this way, if the MTU values that the device receives from
the network in the PCO IPv4 and the RA IPv6 procedures are
different, the user can obtain the correct ipv6 ra_mtu value
and compare the value of ra_mtu and ipv4 mtu, then the device
can use the lower MTU value for both IPv4 and IPv6.

Patch 11:

net/mlx5: DR, Skip source port matching on FDB RX domain
The FDB RX pipe is connected to the wire and the source port for all
incoming packets equals to wire, single uplink port per PF, this means
there is no point of matching on the source port in such case.
Once we recognize such case, we will optimize the RX steering rule.
Note that in such case we clean both source_eswitch_owner_vhca_id and
source_port.

net/mlx5: DR, Add ignore_flow_level support for multi-dest flow tables
When creating an FTE, we might need to create multi-destination flow table,
which is eventually created by FW. In such case, this FW table should
include all the FTE properties as requested by the upper layer, including
the ability to point to another flow table with level lower or equal to
the current table - indicated by the "ignore_flow_level" property.
