- Default value of AIP timer is 1ms, and it is easy for some expanders to
cause IO error. Change the value to max value 65ms to avoid IO error for
those expanders.
- A CQ completion will be reported by HW when 4 CQs have occurred or the
aging timer expires, whichever happens first. Sor serial IO scenario, it
will still wait 8us for every IO before it is reported. So in the
situation, the performance is poor. So to improve it, change the limit
time to the least value.

In previously implement for unicast mac vlan table, the space is

table for each function by software. Each function can only use its
private space and available shared space, avoiding single function

In original codes, the mac vlan table entries are not cleared when

needs to clear the tables itself.

hns uses NAPI for TX completions, so we better let core

Our VF has not implemented the ops for get_port_type. So when we executing
ethtool ethx cmd of VF, hns3_get_link_ksettings will return directly. And
we can not query anything.
To support get_link_ksettings for VF, this patch replaces get_port_type
with get_media_type. If the media type is HNAE3_MEDIA_TYPE_NONE,
hns3_get_link_ksettings will return link information of VF.

net: hns3: Fix tqp array traversal condition for vf
BugLink: https://bugs.launchpad.net/bugs/1810457
There are two tqp_num variables "hdev->tqp_num" and "kinfo->tqp_num"
used in VF. "hdev->tqp_num" is the total tqp number allocated to the
VF, and "kinfo->tqp_num" indicates the tqp number being used by the
VF. Usually the two variables are equal. But for the case hdev->tqp_num
larger than rss_size_max, and num_tc is 1, "kinfo->tqp_num" will be
less than "hdev->tqp_num".
In original codes, "hdev->tqp_num" is always used to traverse the
tqp array of kinfo. It may cause null pointer error when "hdev->tqp_num"
is larger than "kinfo->tqp_num"

net: hns3: Fix for setting speed for phy failed problem
BugLink: https://bugs.launchpad.net/bugs/1810457
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.

When netdev is down, the stack will delete the vlan from
hardware including vlan0, which will cause problem when
doing loopback selftest when netdev is down.
This patch fixes it by always preserving vlan 0 in hardware,
because vlan 0 is defalut vlan, which should always be in
hardware.
