----------------------------------------------------------------------

As RSS indirection table size may be different in different
hardware. Instead of using macro, this value is better to use
device specification which querying from firmware.

BTW, RSS indirection table should be allocated by the queried
size instead the static array.

.get_rss_indir_size in struct hnae3_ae_ops is not used now,
so remove it as well.

In order to query tm info of nodes, priority and qset
for debugging, adds three debugfs files tm_nodes,
tm_priority and tm_qset in newly created tm directory.

Unlike previous debugfs commands, these three files
just support read ops, so they only support to use cat

----------------------------------------------------------------------

Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.

This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure.  So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.

Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.

This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1.  It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.

max rss size, and no more than 128.

For DEVICE_VERSION_V3, the max rss size for PF can be up to

To be compatible with boards using old configure file, the PF

Now we can remove a bunch of identical functions from the drivers and
make them use common dev_page_is_reusable(). All {,un}likely() checks
are omitted since it's already present in this helper.
Also update some comments near the call sites.

net: hns3: refine the VLAN tag handle for port based VLAN · fd9b7335

由 Guojia Liao 提交于 7月 16, 2021

mainline inclusion

commit 592b0179
category: feature
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=592b0179cd498641ae45b9ad4276f5038230f7aa

----------------------------------------------------------------------

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.

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.

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c43abe1a5f83d3afe39f9aea99edfd594add705c

----------------------------------------------------------------------

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.
