We recently changed these two pointers from void pointers to struct
pointers and it breaks the pointer math so now the "txphdr" points
beyond the end of the buffer.

These flags are used to set and test bits like this:
if (!test_bit(HCLGE_PTP_FLAG_TX_EN, &ptp->flags) ||
The issue is that test_bit() takes a bit number like 1, but we are
passing BIT(1) instead and it's testing BIT(BIT(1)). This does not
cause a problem because it is always done consistently and the bit
values are very small.

This patch doesn't affect runtime at all, it's just a correctness issue.
The ptp->info.name[] buffer has 16 characters but the snprintf() limit

100GbE Intel Wired LAN Driver Updates 2021-06-18
Update three of the Intel Ethernet drivers with similar (but not the
same) improvements to simplify the packet type table init, while removing
an unused structure entry. For the ice driver, the table is extended
to 10 bits, which is the hardware limit, and for now is initialized
to zero.
The end result is slightly reduced memory usage, removal of a bunch
of code, and more specific initialization.

}
priv is netdev private data, but it is used
after free_netdev(). It can cause use-after-free when accessing priv
pointer. So, fix it by moving free_netdev() after pci_iounmap()
calls.

Add a couple of memory-barriers to ensure correct ordering of read/write
access to TX BDs.
In xmit_done, we should ensure that reading the additional BD fields are
only done after STS_CTRL_APP0_CMPLT bit is set.
When xmit_done marks the BD as free by setting APP0=0, we need to ensure
that the other BD fields are reset first, so we avoid racing with the xmit
path, which writes to the same fields.
Finally, making sure to read APP0 of next BD after the current BD, ensures
that we see all available buffers.

With the skb pointer piggy-backed on the TX BD, we have a simple and
efficient way to free the skb buffer when the frame has been transmitted.
But in order to avoid freeing the skb while there are still fragments from
the skb in use, we need to piggy-back on the TX BD of the skb, not the
first.
Without this, we are doing use-after-free on the DMA side, when the first
BD of a multi TX BD packet is seen as completed in xmit_done, and the
remaining BDs are still being processed.

The hardware is reporting the type of the hash used for RSS
as a PTYPE field in the receive descriptor. Use this value to set
the skb packet hash type by extending the hash type table to
cover all 10-bits of possible values (requiring some variables
to be changed from u8 to u16), and then use that table to convert
to one of the possible values in enum pkt_hash_types.
While we're here, remove the unused ptype struct value, which
makes table init easier for the zero entries, and use ranged
initializer to remove a bunch of code (works with gcc and clang).
Without this change, the kernel will recalculate the hash in software,
which can consume extra CPU cycles.

However it seems that struct qed_dcbx_operational_params
(dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params
(p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte

On the assumption that the size is wrong (rather than the source structure
type), adjust the memcpy() size argument to be 4 bytes smaller and add

Devices with RMON support has a 16-bit RDRP counter. It provides: "Receive
dropped packets counter. Increments for frames received which are streamed
to system but are later dropped due to lack of system resources."
To handle more than 2^16 dropped packets, a carry bit in CAR1 register is
set on overflow, so we enable irq when this is set, extending the counter
to 2^64 for handling situations where lots of packets are missed (e.g.
during heavy network storms).

Reset only the index part of the mkey and keep the variant part. On
devlink reload, driver recreates mkeys, so the mkey index may change.
Trying to preserve the variant part of the mkey, driver mistakenly
merged the mkey index with current value. In case of a devlink reload,
current value of index part is dirty, so the index may be corrupted.

Running devlink reload command for port in switchdev mode cause
resources to corrupt: driver can't release allocated EQ and reclaim
memory pages, because "rdma" auxiliary device had add CQs which blocks
EQ from deletion.
Erroneous sequence happens during reload-down phase, and is following:
1. detach device - suspends auxiliary devices which support it, destroys
others. During this step "eth-rep" and "rdma-rep" are destroyed,
"eth" - suspended.
2. disable SRIOV - moves device to legacy mode; as part of disablement -
rescans drivers. This step adds "rdma" auxiliary device.
3. destroy EQ table - <failure>.
Driver shouldn't create any device during unload flows. To handle that
implement MLX5_PRIV_FLAGS_DETACH flag, set it on device detach and unset
on device attach. If flag is set do no-op on drivers rescan.

Decapsulation L3 on small inner packets which are less than
64 Bytes was done incorrectly. In small packets there is an
extra padding added in L2 which should not be included in L3
length. The issue was that after decapL3 the extra L2 padding
caused an update on the L3 length.
To avoid this issue the new header is pushed to the beginning
of the packet (offset 0) which should not cause a HW reparse
and update the L3 length.

When auxiliary bus autoprobe is disabled and SF is in ACTIVE state,
on SF port deletion it transitions from ACTIVE->ALLOCATED->INVALID.
When VHCA event handler queries the state, it is already transition
to INVALID state.
In this scenario, event handler missed to delete the SF device.
Fix it by deleting the SF when SF state is INVALID.

E-switch should be able to set the GUID of host PF vport.
Currently it returns an error. This results in below error
when user attempts to configure MAC address of the PF of an
external controller.

External controller PF's MAC address is not read from the device during
vport setup. Fail to read this results in showing all zeros to user
while the factory programmed MAC is a valid value.
$ devlink port show eth1 -jp
{
"port": {
"pci/0000:03:00.0/196608": {
"type": "eth",
"netdev": "eth1",
"flavour": "pcipf",

"pfnum": 0,
"splittable": false,
"function": {
"hw_addr": "00:00:00:00:00:00"
}
}
}
}
Hence, read it when enabling a vport.
After the fix,
