Subject: [External] Re: linux kernel page allocation
The local variable references in shrink_page_list is PAGEREF_RECLAIM_CLEAN
as default. It is for preventing to reclaim dirty pages when CMA try to
migrate pages. Strictly speaking, we don't need it because CMA didn't allow
to write out by .may_writepage = 0 in reclaim_clean_pages_from_list.
The isolate counting is pecpu counter so it would be not huge gain
to work them by batch. Rather than complicating to make them batch,
let's make it more stright-foward via adding the counting logic
into [isolate|putback]_lru_page API.

When "deep" suspend is enabled, all CPUs except the primary CPU
are hotplugged out. Since CPU hotplug is a costly operation,
check if we have to abort the suspend in between each CPU
hotplug. This would improve the system suspend abort latency
upon detecting a wakeup condition.

LINK_UP and LINK_DOWN are two bits of MAC tunnel interrupts, but previous
HNS3 driver didn't handle them. If they were enabled, value of these two
bits will change during link down and link up, which will cause HNS3
driver keep receiving IRQ but can't handle them.

If we add a VF without loading hclgevf.ko and then there is a RAS error
occurs, PCIe AER will call error_detected and slot_reset of all functions,
and will get a NULL pointer when we check ad_dev->ops->handle_hw_ras_error.
This will cause a call trace and failures on handling of

VF VLAN table can only support no more than 256 VLANs. When user
adds too many VLANs, the VF VLAN table will be full, and firmware
will close the VF VLAN table for the function. When VF VLAN table
is full, and user keeps adding new VLANs, it's unnecessary to
configure the VF VLAN

We shouldn't set HNAE3_NONE_RESET bit of the variable that represents a
reset request during handling of MSI-X errors, or may cause issue when
trigger reset.

Since core reset is similar to the global reset, so this
patch removes it and uses global reset to replace it.

Current dwmac4_flow_ctrl will not clear
GMAC_RX_FLOW_CTRL_RFE/GMAC_RX_FLOW_CTRL_RFE bits,
so MAC hw will keep flow control on although expecting
flow control off by ethtool. Add codes to fix it.

issue a rx interrupt once receiving a packet, so the responding time
for rx path will be reduced.
