[PATCH net-next 1/6] net: hns3: Remove the default mask configuration for mac vlan table

[Salil Mehta]

From: Jian Shen <shenjian15@huawei.com>

The default mask configuration has been done by firmware, so the driver
doesn't need to do it any more.

[PATCH net-next 2/6] net: hns3: Clear mac vlan table entries when unload driver or function reset

[Salil Mehta]

From: Jian Shen <shenjian15@huawei.com>

In original codes, the mac vlan table entries are not cleared when
unload hns3 driver. The dirty mac vlan table entries will make the
result of looking up mac vlan table being unexpected.

When doing core reset or global reset, the firmware will clear all
the tables for driver, and driver shouldn't send any commands to
firmware during reset. But when doing function reset, the driver
needs to clear the tables itself.

This patch clears the mac vlan table entries for each client when
unload driver or reset.

[PATCH net-next 3/6] net: hns3: Optimize for unicast mac vlan table

[Salil Mehta]

From: Jian Shen <shenjian15@huawei.com>

In previously implement for unicast mac vlan table, the space is
shared by all the functions, driver does nothing when the space is
exhausted. This patch preallocates the space of unicast mac vlan
table for each function by software. Each function can only use its
private space and available shared space, avoiding single function
exhausts too much space, and other functions are unable to add
unicast mac address.

[PATCH net-next 6/6] net: hns3: Fix for rx vlan id handle to support Rev 0x21 hardware

[Salil Mehta]

From: Jian Shen <shenjian15@huawei.com>

In revision 0x20, we use vlan id != 0 to check whether a vlan tag
has been offloaded, so vlan id 0 is not supported.

In revision 0x21, rx buffer descriptor adds two bits to indicate
whether one or more vlan tags have been offloaded, so vlan id 0
is valid now.

This patch seperates the handle for vlan id 0, add vlan id 0 support
for revision 0x21.

Fixes: 5b5455a9ed5a ("net: hns3: Add STRP_TAGP field support for hardware revision 0x21")
