Claudiu Beznea says:

====================
net: macb: add support for sama7g5

This series adds support for SAMA7G5 Ethernet interfaces: one 10/100Mbps
and one 1Gbps interfaces.

Along with it I also included a fix to disable clocks for SiFive FU540-C000
on failure path of fu540_c000_clk_init().

Thank you,
Claudiu Beznea

Changed in v3:
- use clk_bulk_disable_unprepare in patch 3/8
- corrected clang compilation warning in patch 3/8
- revert changes in macb_clk_init() in patch 3/8

Changes in v2:
- introduced patch "net: macb: add function to disable all macb clocks" and
  update patch "net: macb: unprepare clocks in case of failure" accordingly
- collected tags

SAMA7G5's ethernet IPs TX clock could be provided by its generic clock or

Shay Agroskin f1a2558913 net: ena: introduce ndo_xdp_xmit() function for XDP_REDIRECT
This patch implements the ndo_xdp_xmit() net_device function which is
called when a packet is redirected to this driver using an
XDP_REDIRECT directive.

The function receives an array of xdp frames that it needs to xmit.
The TX queues that are used to xmit these frames are the XDP
queues used by the XDP_TX flow. Therefore a lock is added to synchronize
both flows (XDP_TX and XDP_REDIRECT).

Shay Agroskin a318c70ad1 net: ena: introduce XDP redirect implementation
This patch adds a partial support for the XDP_REDIRECT directive which
instructs the driver to pass the packet to an interface specified by the
program. The directive is passed to the driver by calling bpf_redirect()
or bpf_redirect_map() functions from the eBPF program.

To lay the ground for integration with the existing XDP TX
implementation the patch removes the redundant page ref count increase
in ena_xdp_xmit_frame() and then decrease in ena_clean_rx_irq(). Instead
it only DMA unmaps descriptors for which XDP TX or REDIRECT directive
was received.

The XDP Redirect support is still missing .ndo_xdp_xmit function
implementation, which allows to redirect packet to an ENA interface,
which would be added in a later patch.

The function includes the
    - lock aquire (on 32bit machines)
    - stat increase
    - lock release (on 32bit machines)

line sequence that is ubiquitous across the driver.

The function increases a single stat at a time and several stats which
are increased together weren't put into a function to avoid
calling the function several times for each stat which looks bad and
might decrease performance.

Shay Agroskin da580ca8de net: ena: add device distinct log prefix to files
ENA logs are adjusted to display the full ENA representation to
distinct each ENA device in case of multiple interfaces.
Using netdev_err/warn and dev_info functions for logging provides
uniform printing with clear distinction of the device and interface.

This patch changes all printing in ena_com files to use netev_* logging
functions except for messages of info level. Log functions of that level
would be printed with dev_info because of the early stage they are
called in when net_device struct isn't yet registered.

To allow using netdev_* functions in all ena_com functions, a pointer to
the net_device was added to ena_com_dev struct.

The patch also adds some log messages to make driver debugging easier.

Shay Agroskin ce74496a15 net: ena: use constant value for net_device allocation
The patch changes the maximum number of RX/TX queues it advertises to
the kernel (via alloc_etherdev_mq()) from a value received from the
device to a constant value which is the minimum between 128 and the
number of CPUs in the system.

By allocating the net_device struct with a constant number of queues,
the driver is able to allocate it at a much earlier stage, before
calling any ena_com functions. This would allow to make all log prints
in ena_com to use netdev_* log functions instead or current pr_* ones.

Note:
netdev_* prints in ena_com functions that are called before
net_device registration in ena_probe() might print messages that are
a bit ugly (with strings like "(unnamed net_device) (uninitialized)").
However we decided to use netdev_* prints in these functions anyway,
for the sake of getting better messages later, when ena_com functions
are called after ena_probe() form other parts of the driver.
See discussion about this decision in [1].

Andrea Mayer 9125abe7b9 vrf: handle CONFIG_IPV6 not set for vrf_add_mac_header_if_unset()
The vrf_add_mac_header_if_unset() is defined within a conditional
compilation block which depends on the CONFIG_IPV6 macro.
However, the vrf_add_mac_header_if_unset() needs to be called also by IPv4
related code and when the CONFIG_IPV6 is not set, this function is missing.
As a consequence, the build process stops reporting the error:

 ERROR: implicit declaration of function 'vrf_add_mac_header_if_unset'

The problem is solved by *only* moving functions
vrf_add_mac_header_if_unset() and vrf_prepare_mac_header() out of the
conditional block.

David S. Miller 25fd263473 Merge branch 'GVE-Raw-Addressing'
David Awogbemil says:

====================
GVE Raw Addressing
Patchset description:
This  patchset introduces "raw addressing" mode to the GVE driver.
Previously (in "queue_page_list" or "qpl" mode), the driver would
pre-allocate and dma_map buffers to be used on egress and ingress.
On egress, it would copy data from the skb provided to the
pre-allocated buffers - this was expensive.
In raw addressing mode, the driver can avoid this copy and simply
dma_map the skb's data so that the NIC can use it.
On ingress, the driver passes buffers up to the networking stack and
then frees and reallocates buffers when necessary instead of using
skb_copy_to_linear_data.
Patch 3 separates the page refcount tracking mechanism
into a function gve_rx_can_recycle_buffer which uses get_page - this will
be changed in a future patch to eliminate the use of get_page in tracking
page refcounts.

Changes from v9:
  Patch 4: Use u64, not u32 for new tx stat counters.
