CVE: NA

The function hclge_tm_dwrr_cfg() will be called twice in function
hclge_ieee_setets() when map_changed is true, the calling flow is
hclge_ieee_setets()
    hclge_map_update()
    |   hclge_tm_schd_setup_hw()
    |       hclge_tm_dwrr_cfg()
    hclge_notify_init_up()
    hclge_tm_dwrr_cfg()

It is no need to call hclge_tm_dwrr_cfg() twice actually, so just
return after calling hclge_notify_init_up().

Currently, function hclge_check_port_speed() uses switch/case statement
to get speed bit according to speed. To reuse this part of code and
improve code readability and maintainability, add a new function
hclge_get_speed_bit() to get speed bit according to map relationship
of speed and speed bit defined in array speed_bit_map.

bugzilla: https://gitee.com/openeuler/kernel/issues/I49LXW
CVE: NA

-------------------------------------------------

Page owner of pages used by page owner itself used is missing on arm32
targets.  The reason is dummy_handle and failure_handle is not initialized
correctly.  Buddy allocator is used to initialize these two handles.
However, buddy allocator is not ready when page owner calls it.  This
change fixed that by initializing page owner after buddy initialization.

The working flow before and after this change are:
original logic:
 1. allocated memory for page_ext(using memblock).
 2. invoke the init callback of page_ext_ops like page_owner(using buddy
    allocator).
 3. initialize buddy.

after this change:
 1. allocated memory for page_ext(using memblock).
 2. initialize buddy.
 3. invoke the init callback of page_ext_ops like page_owner(using buddy
    allocator).

with the change, failure/dummy_handle can get its correct value and page
owner output for example has the one for page owner itself:

  Page allocated via order 2, mask 0x6202c0(GFP_USER|__GFP_NOWARN),

commit 029ee6b1
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I46N7D
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=029ee6b14356b94120bedb852dcdaefc0a282cf1

----------------------------------------------------------------------

Currently, there are many drivers who support CQE mode configuration,
some configure it as a fixed when initialized, some provide an
interface to change it by ethtool private flags. In order to make it
more generic, add two new 'ETHTOOL_A_COALESCE_USE_CQE_TX' and
'ETHTOOL_A_COALESCE_USE_CQE_RX' coalesce attributes, then these
parameters can be accessed by ethtool netlink coalesce uAPI.

Also add an new structure kernel_ethtool_coalesce, then the
new parameter can be added into this struct.

commit 8c1671e0
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I46N6O
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8c1671e0d13d4a0ba4fb3a0da932bf3736d7ff73

----------------------------------------------------------------------

Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.

for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on

To fix this problem, just returns user's PFC config parameter saved in
driver.

In bond 4, when the link goes down and up repeatedly, the bond may get an
unknown speed, and then this port can not work.

The driver notify netif_carrier_on() before update the link state, when the
bond receive carrier on, will query the speed of the port, if the query
operation happens before updating the link state, will get an unknown
speed. So need to notify netif_carrier_on() after update the link state.

There is at most one TPM chip in the system and one measurement list
associated to one of its PCRs. IMA namespace IDs can be re-used after
namespace is destroyed. The per namespace boot aggregate entry marks
the moment of the ima namespace creation. It is useful when host's
root parses the global measurement list to find entries for destroyed
containers. If the ima namespace ID is reused, the user will know, that
