From: Peng Li <lipeng321@huawei.com>
All irq will float to cpu0 if do not set irq affinity.
This patch adds default irq affinity in hns3 driver, users can
also change the irq affinity in OS.

Tx descriptors as possible in a irq.

All pf have permission to read packet statistics of public in hardware,
but the read operation will clear registers which cause statistical
inaccuracy.
This patch removes all packet statistics of public.

We clear STATE_DOWN bit of hdev state when starting net, but do not set
it again when stopping net. It causes that the net is down, but hdev state
is still up. STATE_DOWN bit of hdev state should be set when stopping net.

By default, HW link status is up. If hclge_update_link_status is called
before net up, driver will print "link up". It is not suitable. hdev
state check is needed when getting link status.

The function of genphy_read_status is that reading phy information
from HW and using these information to update SW variable. If user
is using ethtool to setting the speed of phy and service task is calling
by hclge_get_mac_phy_link, the result of speed setting is uncertain.
Because ethtool cmd will modified phydev and hclge_get_mac_phy_link also
will modified phydev.
Because phy state machine will update phy link periodically, we can
just use phydev->link to check the link status. This patch removes
function call of genphy_read_status. To ensure accuracy, this patch
adds a phy state check. If phy state is not PHY_RUNNING, we consider
link is down. Because in some scenarios, phydev->link may be link up,
but phy state is not PHY_RUNNING. This is just an intermediate state.
In fact, the link is not ready yet.

According to hardware's description, the head pointer register should
be written before the tail pointer register while initializing the vf
command queue. Otherwise, it may trigger an interrupt even though there
is no command received.

If initialize client failed or finish uninitializing client, we should
clear the client pointer. It may cause unexpected result when use
uninitialized client. Meanwhile, we also should check whether client
exist when uninitialize it.

When roce is loaded before nic, the roce client will not be initialized
until nic client is initialized, but roce init flag is set before it.
Furthermore, in this case of nic initialized success and roce failed,
the nic init flag is not set, and roce init flag is not cleared.
This patch fixes it by set init flag only after the client is initialized
successfully.

From: Jian Shen <shenjian15@huawei.com>
So far all the places calling hclge_tm_q_to_qs_map_cfg() are assigning
an u16 type value to "q_id", and in the processing of
hclge_tm_q_to_qs_map_cfg(), it also converts the "q_id" to le16.
The max tqp number for pf can be more than 256, we should use "u16" to
store the queue id, instead of "u8", which may cause data lost.
Fixes: 848440544b41 ("net: hns3: Add support of TX Scheduler & Shaper to HNS3 driver")
