[ Upstream commit 8619593634cbdf5abf43f5714df49b04e4ef09ab ]
I found the following bug in my fuzzer:

Since this bug has been confirmed to be caused by insufficient verification
of conn_rsp_epid, I think it would be appropriate to add a range check for
conn_rsp_epid to htc_connect_service() to prevent the bug from occurring.

[ Upstream commit dd6e972cc5890d91d6749bb48e3912721c4e4b25 ]
The kTLS tx handling code is using a mix of get_page() and
page_ref_inc() APIs to increment the page reference. But on the release
path (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.
This is an issue when using pages from large folios: the get_page()
references are stored on the folio page while the page_ref_inc()
references are stored directly in the given page. On release the folio
page will be dereferenced too many times.
This was found while doing kTLS testing with sendfile() + ZC when the
served file was read from NFS on a kernel with NFS large folios support
(commit 49b29a573da8 ("nfs: add support for large folios")).

commit 73f476aa1975bae6a792b340f5b26ffcfba869a6 upstream.
The previous implementation of .handle_interrupt() did not take into
account the fact that all the interrupt status registers should be
acknowledged since multiple interrupt sources could be asserted.
Fix this by reading all the status registers before exiting with
IRQ_NONE or triggering the PHY state machine.

DP83848 datasheet (section 4.7.2) indicates that the reset pin should be
toggled after the clocks are running. Add the PHY_RST_AFTER_CLK_EN to
make sure that this indication is respected.
In my experience not having this flag enabled would lead to, on some
boots, the wrong MII mode being selected if the PHY was initialized on
the bootloader and was receiving data during Linux boot.

In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.

These functions are currently used by phy_interrupt() to either signal
an error condition or to trigger the link state machine. In an attempt
to actually support shared PHY IRQs, export these two functions so that
the actual PHY drivers can use them.

[ Upstream commit df3dff8ab6d79edc942464999d06fbaedf8cdd18 ]
When the driver is uninstalled and the VF is disabled concurrently, a
kernel crash occurs. The reason is that the two actions call function
pci_disable_sriov(). The num_VFs is checked to determine whether to
release the corresponding resources. During the second calling, num_VFs
is not 0 and the resource release function is called. However, the
corresponding resource has been released during the first invoking.
Therefore, the problem occurs:

[ Upstream commit badccd49b93bb945bf4e5cc8707db67cdc5e27e5 ]
The MAC address of VF can be configured through the mailbox mechanism of
ENETC, but the previous implementation forgot to set the MAC address in
net_device, resulting in the SMAC of the sent frames still being the old
MAC address. Since the MAC address in the hardware has been changed, Rx
cannot receive frames with the DMAC address as the new MAC address. The
most obvious phenomenon is that after changing the MAC address, we can
see that the MAC address of eno0vf0 has not changed through the "ifconfig
eno0vf0" command and the IP address cannot be obtained .
