302a7cad54 net: macb: Kconfig: Rename Atmel to Cadence
The help text makes it look like NET_VENDOR_CADENCE enables support for
Atmel devices, when in reality it's a driver written by Atmel that
supports Cadence devices.  This may confuse users that have this device
on a non-Atmel SoC.

The fix is just s/Atmel/Cadence/, but I did go and re-wrap the Kconfig
help text as that change caused it to go over 80 characters.

c536a9aa7c net: macb: Kconfig: Make MACB depend on COMMON_CLK
commit c218ad5590 ("macb: Add support for SiFive FU540-C000") added a
dependency on the common clock framework to the macb driver, but didn't
express that dependency in Kconfig.  As a result macb now fails to
compile on systems without COMMON_CLK, which specifically causes a build
failure on powerpc allyesconfig.

This patch adds the dependency, which results in the macb driver no
longer being selectable on systems without the common clock framework.
All known systems that have this device already support the common clock
framework, so this should not cause trouble for any uses.  Supporting
both the FU540-C000 and systems without COMMON_CLK is quite ugly.

I've build tested this on powerpc allyesconfig and RISC-V defconfig
(which selects MACB), but I have not even booted the resulting kernels.

48dd73d08d net: aquantia: fix vlans not working over bridged network
In configuration of vlan over bridge over aquantia device
it was found that vlan tagged traffic is dropped on chip.

The reason is that bridge device enables promisc mode,
but in atlantic chip vlan filters will still apply.
So we have to corellate promisc settings with vlan configuration.

The solution is to track in a separate state variable the
need of vlan forced promisc. And also consider generic
promisc configuration when doing vlan filter config.

8d212ff057 net/mlx5e: Specifying known origin of packets matching the flow
In vport metadata matching, source port number is replaced by metadata.
While FW has no idea about what it is in the metadata, a syndrome will
happen. Specify a known origin to avoid the syndrome.
However, there is no functional change because ANY_VPORT (0) is filled
in flow_source, the same default value as before, as a pre-step towards
metadata matching for fast path.
There are two other values can be filled in flow_source. When setting
0x1, packet matching this rule is from uplink, while 0x2 is for packet
from other local vports.

7445cfb116 net/mlx5: E-Switch, Tag packet with vport number in VF vports and uplink ingress ACLs
When a dual-port VHCA sends a RoCE packet on its non-native port, and the
packet arrives to its affiliated vport FDB, a mismatch might occur on the
rules that match the packet source vport as it is not represented by single
VHCA only in this case. So we change to match on metadata instead of source
vport.
To do that, a rule is created in all vports and uplink ingress ACLs, to
save the source vport number and vhca id in the packet's metadata in order
to match on it later.
The metadata register used is the first of the 32-bit type C registers. It
can be used for matching and header modify operations. The higher 16 bits
of this register are for vhca id, and the lower 16 ones is for vport
number.
This change is not for dual-port RoCE only. If HW and FW allow, the vport
metadata matching is enabled by default.

fae6cad17c i40e/i40e_virtchnl_pf: Use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct virtchnl_iwarp_qvlist_info {
	...
        struct virtchnl_iwarp_qv_info qv_info[1];
};

size = sizeof(struct virtchnl_iwarp_qvlist_info) + (sizeof(struct virtchnl_iwarp_qv_info) * count;
instance = kzalloc(size, GFP_KERNEL);

and

struct virtchnl_vf_resource {
	...
        struct virtchnl_vsi_resource vsi_res[1];
};

size = sizeof(struct virtchnl_vf_resource) + sizeof(struct virtchnl_vsi_resource) * count;
instance = kzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, qv_info, count), GFP_KERNEL);

and

instance = kzalloc(struct_size(instance, vsi_res, count), GFP_KERNEL);

Notice that, in the first case above, variable size is not necessary, hence it
is removed.

This code was detected with the help of Coccinelle.

15369ac3e3 i40e: Fix descriptor count manipulation
Changing descriptor count via 'ethtool -G' is not persistent across resets.
When PF reset occurs, we roll back to the default value of vsi->num_desc,
which is used then in i40e_alloc_rings to set descriptor count. XDP does a
PF reset so when user has changed the descriptor count and load XDP
program, the default count will be back there.

To fix this:
  * introduce new VSI members - num_tx_desc and num_rx_desc in favour of
    num_desc
  * set them in i40e_set_ringparam to user's values
  * set them to default values in i40e_set_num_rings_in_vsi only when they
    don't have previous values

I40E_FLAG_DISABLE_FW_LLDP flag in i40e_init_pf_dcb(). The function
i40e_update_dcb_config() in i40e_main.c is a temporary solution which
will be later renamed to i40e_init_dcb() in the i40e_dcb module. Also
logging was extended to make visible if f/w LLDP agent is running or not
and always log a message when DCB was not initialized. Without this
patch for new f/w versions f/w LLDP agent status was always read
from NVM as disabled and DCB initialization failed without
clear reason in logs.

177d935a13 net: stmmac: Fix crash observed if PHY does not support EEE
If the PHY does not support EEE mode, then a crash is observed when the
ethernet interface is enabled. The crash occurs, because if the PHY does
not support EEE, then although the EEE timer is never configured, it is
still marked as enabled and so the stmmac ethernet driver is still
trying to update the timer by calling mod_timer(). This triggers a BUG()
in the mod_timer() because we are trying to update a timer when there is
no callback function set because timer_setup() was never called for this
timer.

The problem is caused because we return true from the function
stmmac_eee_init(), marking the EEE timer as enabled, even when we have
not configured the EEE timer. Fix this by ensuring that we return false
if the PHY does not support EEE and hence, 'eee_active' is not set.

72fcd2bed7 net: hns3: fixes wrong place enabling ROCE HW error when loading
The ROCE HW errors should only be enabled when initializing ROCE's
client, the current code enable it no matter initializing NIC or
ROCE client.

So this patch fixes it.

9d5e67d1c1 net: hns3: remove override_pci_need_reset
We add override_pci_need_reset to prevent redundant and unwanted PF
resets if a RAS error occurs in commit 69b51bbb03 ("net: hns3: fix
to stop multiple HNS reset due to the AER changes").

Now in HNS3 driver, we use hw_err_reset_req to record reset level that
we need to recover from a RAS error. This variable cans solve above
issue as override_pci_need_reset, so this patch removes
override_pci_need_reset.

2253db16f8 net: hns3: code optimizaition of hclge_handle_hw_ras_error()
This patch optimizes hclge_handle_hw_ras_error() to make the code logic
clearer.
1. If there was no NIC or Roce RAS when we read
   HCLGE_RAS_PF_OTHER_INT_STS_REG, we return directly.
2. Because NIC and Roce RAS may occurs at the same time, so we should
   check value of revision at first before we handle Roce RAS instead
   of only checking it in branch of no NIC RAS is detected.
3. Check HCLGE_STATE_RST_HANDLING each time before we want to return
   PCI_ERS_RESULT_NEED_RESET.
4. Remove checking of HCLGE_RAS_REG_NFE_MASK and
   HCLGE_RAS_REG_ROCEE_ERR_MASK because if hw_err_reset_req is not
   zero, it proves that we have set it in handling of NIC or Roce RAS.

fe4144d47e net: hns3: sync VLAN filter entries when kill VLAN ID failed
When HW is resetting, firmware is unable to handle commands
from driver. So if remove VLAN device from stack at this time,
it will fail to remove the VLAN ID from HW VLAN filter, then
the VLAN filter status is unsynced with stack.

This patch fixes it by recording the VLAN ID delete failed,
and removes them again when reset complete.

30d8177e8a bonding: Always enable vlan tx offload
We build vlan on top of bonding interface, which vlan offload
is off, bond mode is 802.3ad (LACP) and xmit_hash_policy is
BOND_XMIT_POLICY_ENCAP34.

Because vlan tx offload is off, vlan tci is cleared and skb push
the vlan header in validate_xmit_vlan() while sending from vlan
devices. Then in bond_xmit_hash, __skb_flow_dissect() fails to
get information from protocol headers encapsulated within vlan,
because 'nhoff' is points to IP header, so bond hashing is based
on layer 2 info, which fails to distribute packets across slaves.

This patch always enable bonding's vlan tx offload, pass the vlan
packets to the slave devices with vlan tci, let them to handle
vlan implementation.
