[PATCH V2 net-next 0/3] net: hns3: updates for -next

[Huazhong Tan]

There are some updates for the HNS3 ethernet driver.

#1 supports an extended promiscuous command which makes
promiscuous configuration more flexible, #2 adds ethtool
private flags to control whether enable tx unicast promisc.
#3 refine the vlan tag handling for port based vlan.

change log:
V2: modifies #2 suggested by Jakub Kicinski.
    fixes some spelling mistake in #3.

[PATCH V2 net-next 1/3] net: hns3: add support for extended promiscuous command

[Huazhong Tan]

From: Guojia Liao <liaoguojia@huawei.com>

For DEVICE_VERSION_V2, the hardware supports enable tx and rx
promiscuous separately. But tx or rx promiscuous is active for
unicast, multicast and broadcast promiscuous simultaneously.
To support traffics between functions belong to the same port,
we always enable tx promiscuous for broadcast promiscuous, so
tx promiscuous for unicast and multicast promiscuous is also
enabled.

For DEVICE_VERSION_V3, the hardware decouples the above
relationship. Tx unicast promiscuous, rx unicast promiscuous,
tx multicast promiscuous, rx multicast promiscuous, tx broadcast
promiscuous and rx broadcast promiscuous can be enabled separately.

So add support for the new promiscuous command.

[PATCH V2 net-next 2/3] net: hns3: add priv flags support to switch limit promisc mode

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

Currently, the tx unicast promisc is always enabled when promisc
mode on. If tx unicast promisc on, a function will receive all
unicast packet from other functions belong to the same port.
Add a ethtool private flag to control whether enable tx
unicast promisc. Then the function is able to filter the
unknown unicast packets from other function.

[PATCH V2 net-next 3/3] net: hns3: refine the VLAN tag handle for port based VLAN

[Huazhong Tan]

From: Guojia Liao <liaoguojia@huawei.com>

For DEVICE_VERSION_V2, the hardware only supports max two layer
VLAN tags, including port based tag inserted by hardware, tag in
tx buffer descriptor(get from skb->tci) and tag in packet.

For transmit packet:
If port based VLAN disabled, and vf driver gets a VLAN tag from
skb, the VLAN tag must be filled to the Outer_VLAN_TAG field
(tag near to DMAC) of tx buffer descriptor, otherwise it may
be inserted after the tag in packet.

If port based VLAN enabled, and vf driver gets a VLAN tag from
skb, the VLAN tag must be filled to the VLAN_TAG field (tag
far to DMAC) of tx buffer descriptor, otherwise it may be
conflicted with port based VLAN, and raise a hardware error.

For receive packet:
The hardware will strip the VLAN tags and fill them in the rx
buffer descriptor, no matter port based VLAN enable or not.
Because port based VLAN tag is useless for stack, so vf driver
needs to discard the port based VLAN tag get from rx buffer
descriptor when port based VLAN enabled.

So vf must know about the port based VLAN state.

For DEVICE_VERSION_V3, the hardware provides some new
configuration to improve it.

For transmit packet:
When enable tag shift mode, hardware will handle the VLAN tag
in outer_VLAN_TAG field as VLAN_TAG, so it won't conflict with
port based VLAN. And hardware also make sure the tag before
the tag in packet. So vf driver doesn't need to specify the tag
position according to the port based VLAN state anymore.

For receive packet:
When enable discard mode, hardware will strip and discard the
port based VLAN tag, so vf driver doesn't need to identify it
from rx buffer descriptor.

So modify the port based VLAN configuration, simplify the process
for vf handling the VLAN tag.
