====================
selftests: drv-net: stats: use skip instead of xfail
Alex posted support for configuring pause frames in fbnic. This flipped
the pause stats test from xfail to fail. Because CI considered xfail as
pass it now flags the test as failing. This shouldn't happen. Also we
currently report pause and FEC tests as passing on virtio which doesn't
make sense.

XFAIL is considered a form of a pass by our CI. For HW devices returning
XFAIL for unsupported features is counter-productive because our CI
knows not to expect any HW test to pass until it sees 10 passes in a row.
If we return xfail the test shows up as pass even if the device doesn't
support the feature. netdevsim supports all features necessary for
the stats test so there is no concern about running the test in SW mode.
Make the test skip rather than xfail if driver doesn't support FEC or pause.

Small adjustments to make pylint happy.
One warning about unused argument remains because the test uses
global variables rather than attaching netlink sockets to cfg.
Fixing this would be too much of a change for a linter fix commit
like this one.

Difference between sock_i_uid() and sk_uid() is that
after sock_orphan(), sock_i_uid() returns GLOBAL_ROOT_UID
while sk_uid() returns the last cached sk->sk_uid value.
None of sock_i_uid() callers care about this.
Use sk_uid() which is much faster and inlined.
Note that diag/dump users are calling sock_i_ino() and
can not see the full benefit yet.

I tried to fix the stack usage in this function a couple of years ago,
but there is still a problem with the latest gcc versions in some
configurations:
net/caif/cfctrl.c:553:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]
Reduce this once again, with a separate cfctrl_link_setup() function that
holds the bulk of all the local variables. It also turns out that the
param[] array that takes up a large portion of the stack is write-only
and can be left out here.

With sanitizers enabled, this function uses a lot of stack, causing
a harmless warning:
lib/test_objagg.c: In function 'test_hints_case.constprop':
lib/test_objagg.c:994:1: error: the frame size of 1440 bytes is larger than 1408 bytes [-Werror=frame-larger-than=]
Most of this is from the two 'struct world' structures. Since most of
the work in this function is duplicated for the two, split it up into
separate functions that each use one of them.
The combined stack usage is still the same here, but there is no warning
any more, and the code is still safe because of the known call chain.

lpc18xx uses plat_dat->mac_interface, despite wanting to validate the
PHY interface. Checking the DT files (arch/arm/boot/dts/nxp/lpc/), none
of them specify mac-mode which means mac_interface and phy_interface
will be identical.
mac_interface is only used when there is some kind of MII converter
between the DesignWare MAC and PHY, and describes the interface mode
that the DW MAC needs to use, whereas phy_interface describes the
interface mode that the PHY uses.
Noting that lpc18xx only supports MII and RMII interface modes, switch
this glue driver to use plat_dat->phy_interface, and to mark that the
mac_interface is not used, explicitly set it to PHY_INTERFACE_MODE_NA.
The latter is safe as the only user of mac_interface for this platform
would be in stmmac_check_pcs_mode(), which only checks for RGMII or
SGMII.

Add support for the IPQ5018 Internal GE PHY
The IPQ5018 SoC contains an internal Gigabit Ethernet PHY with its
output pins that provide an MDI interface to either an external switch
in a PHY to PHY link architecture or directly to an attached RJ45
connector.
The PHY supports 10BASE-T/100BASE-TX/1000BASE-T link modes in SGMII

The LDO controller found in the IPQ5018 SoC needs to be enabled to drive
power to the CMN Ethernet Block (CMN BLK) which the GE PHY depends on.
The LDO must be enabled in TCSR by writing to a specific register.
In a phy to phy architecture, DAC values need to be set to accommodate

Document the IPQ5018 Internal Gigabit Ethernet PHY found in the IPQ5018
SoC. Its output pins provide an MDI interface to either an external
switch in a PHY to PHY link scenario or is directly attached to an RJ45
connector.
The PHY supports 10/100/1000 mbps link modes, CDT, auto-negotiation and
802.3az EEE.
For operation, the LDO controller found in the IPQ5018 SoC for which
there is provision in the mdio-4019 driver.
Two common archictures across IPQ5018 boards are:
1. IPQ5018 PHY --> MDI --> RJ45 connector
2. IPQ5018 PHY --> MDI --> External PHY
In a phy to phy architecture, the DAC needs to be configured to
accommodate for the short cable length. As such, add an optional boolean
property so the driver sets preset DAC register values accordingly.

All drivers have been converted. Stop using the rxnfc fallbacks
for Rx Flow Hashing configuration.
Joe pointed out in earlier review that in ethtool_set_rxfh()
we need both .get_rxnfc and .get_rxfh_fields, because we need
both the ring count and flow hashing (because we call
ethtool_check_flow_types()). IOW the existing check added

Correct the endianness annotation of port assignments:
A host byte order value (RDS_TCP_PORT) is correctly converted to
network byte order (big endian) using htons. But it is then cast back to
host byte order before assigning to a variable that expects a big endian
value. Address this by dropping the cast.
This is not a bug because, while the endian annotation is changed by
this patch, the assigned value is unchanged.
Also correct the endianness of address assignment.
A host byte order value (INADDR_ANY) is incorrectly assigned as-is to
a variable that expects a big endian value. Address this by converting
the value to network byte order (big endian).
This is not a bug because INADDR_ANY is 0, which is isomorphic
with regards to endian conversions. IOW, while the endian annotation
is changed by this patch, the assigned value is unchanged.
Incorrect endian annotations appear to date back to IPv4-only code added
by commit 70041088e3b9 ("RDS: Add TCP transport to RDS").

====================
gve: XDP TX and redirect support for DQ RDA
A previous patch series[1] introduced the ability to process XDP buffers
to the DQ RDA queue format. This is a follow-up patch series to
introduce XDP_TX and XDP_REDIRECT support and expose XDP support to the
kernel.

This patch adds support for XDP_TX and XDP_REDIRECT for the DQ RDA
queue format. To appropriately support transmission of XDP frames, a
new pending packet type GVE_TX_PENDING_PACKET_DQO_XDP_FRAME is
introduced for completion handling, as there was a previous assumption
that completed packets would be SKBs.
XDP_TX handling completes the basic XDP actions, so the feature is
recorded accordingly. This patch also enables the ndo_xdp_xmit callback
allowing DQ to handle XDP_REDIRECT packets originating from another
interface.
The XDP spinlock is moved to common TX ring fields so that it can be
used in both GQ and DQ. Originally, it was in a section which was
mutually exclusive for GQ and DQ.
In summary, 3 XDP features are exposed for the DQ RDA queue format:
1) NETDEV_XDP_ACT_BASIC
2) NETDEV_XDP_ACT_NDO_XMIT
3) NETDEV_XDP_ACT_REDIRECT
Note that XDP and header-data split are mutually exclusive for the time
being due to lack of multi-buffer XDP support.
This patch does not add support for the DQ QPL format. That is to come
in a future patch series.

This patch performs various minor DQO TX datapath refactors in
preparation for adding XDP_TX and XDP_REDIRECT support. The following
refactors are performed:
1) gve_tx_fill_pkt_desc_dqo() relies on a SKB pointer to
get whether checksum offloading should be enabled. This won't work
for the XDP case, which does not have a SKB. This patch updates the
method to use a boolean representing whether checksum offloading
should be enabled directly.
2) gve_maybe_stop_dqo() contains some synchronization between the true
TX head and the cached value, a synchronization which is common for
XDP queues and normal netdev queues. However, that method is reserved
for netdev TX queues. To avoid duplicate code, this logic is factored
out into a new method, gve_has_tx_slots_available().
3) gve_tx_update_tail() is added to update the TX tail, a functionality
that will be common between normal TX and XDP TX codepaths.

In preparation for XDP DQ support, the gve_xdp_xmit callback needs to
be generalized for all queue formats. This patch renames the GQ-specific
function to gve_xdp_xmit_gqi, and introduces a new gve_xdp_xmit callback
which branches on queue format.

rvu_mbox_init function makes use of error path for
freeing memory which are local to the function in
both success and failure conditions. This is unusual hence
fix it by returning zero on success. With new cn20k code this
is freeing valid memory in success case also.
