When serdes lane support setting 25Gb/s or 50Gb/s speed and user wants to
set port speed as 50Gb/s, it can be setted as one 50Gb/s serdes lane or
two 25Gb/s serdes lanes.
So, this patch adds support to query and set lane number by ethtool
to satisfy this scenario.

Currently, the debugfs mechanism is that all functions share a
global variable to save the pointer for obtaining data. When
different functions concurrently access the same file node,
repeated release exceptions occur. Therefore, the granularity
of the pointer for storing the obtained data is adjusted to be
private for each function.

Currently, when user queries page pool info by debugfs command

Create a single file "coalesce_info" for it, and query it by

Currently, there are two ways for PF to set the unicast MAC address space
size: specified by config parameters in firmware or set to default value.
That's mean if the config parameters in firmware is zero, driver will
divide the whole unicast MAC address space equally to 8 PFs. However, in
this case, the unicast MAC address space will be wasted a lot when the
hardware actually has less then 8 PFs. And in the other hand, if one PF has
much more VFs than other PFs, then each function of this PF will has much
less address space than other PFs.
In order to ameliorate the above two situations, introduce the third way
of unicast MAC address space assignment: firmware divides the whole unicast
MAC address space equally to functions of all PFs, and calculates the space
size of each PF according to its function number. PF queries the space size
by the querying device specification command when in initialization
process.
The third way assignment is lower priority than specified by config
parameters, only if the config parameters is zero can be used, and if
firmware does not support the third way assignment, then driver still
divides the whole unicast MAC address space equally to 8 PFs.

Currently rx page will be reused to receive future packet when
the stack releases the previous skb quickly. If the old page
can not be reused, a new page will be allocated and mapped,
which comsumes a lot of cpu when IOMMU is in the strict mode,
especially when the application and irq/NAPI happens to run on
the same cpu.
So allocate a new frag to memcpy the data to avoid the costly
IOMMU unmapping/mapping operation, and add "frag_alloc_err"
and "frag_alloc" stats in "ethtool -S ethX" cmd.
The throughput improves above 50% when running single thread of
iperf using TCP when IOMMU is in strict mode and iperf shares the
same cpu with irq/NAPI(rx_copybreak = 2048 and mtu = 1500).

when the packet or frag size is small, it causes both security and
performance issue. As dma can't map sub-page, this means some extra
kernel data is visible to devices. On the other hand, the overhead
of dma map and unmap is huge when IOMMU is on.
So add a queue based tx shared bounce buffer to memcpy the small
packet when the len of the xmitted skb is below tx_copybreak.
Add tx_spare_buf_size module param to set the size of tx spare
buffer, and add set/get_tunable to set or query the tx_copybreak.
The throughtput improves from 30 Gbps to 90+ Gbps when running 16
netperf threads with 32KB UDP message size when IOMMU is in the
strict mode(tx_copybreak = 2000 and mtu = 1500).

Previously, with hardware limitation, the port VLAN filter are
effective for both PF and its VFs simultaneously, so a single
function is not able to enable/disable separately, and the VLAN
filter state is default enabled. Now some device supports each
function to bypass port VLAN filter, then each function can
switch VLAN filter separately. Add capability flag to check
whether the device supports modify VLAN filter state. If flag
on, user will be able to modify the VLAN filter state by ethtool
-K.
Furtherly, the default VLAN filter state is also changed
according to whether non-zero VLAN used. Then the device can
receive packet with any VLAN tag if only VLAN 0 used.
The function hclge_need_enable_vport_vlan_filter() is used to
help implement above changes. And the VLAN filter handle for
promisc mode can also be simplified by this function.
