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.

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 70041088e3 ("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.

====================
Signed-off-by: David S. Miller <davem@davemloft.net>
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.

Currently, there is no convenient way to see the info that the
ref_tracking infrastructure collects. Attempt to create a file in
debugfs when called from ref_tracker_dir_init().
The file is given the name "class@%px", as having the unmodified address
is helpful for debugging. This should be safe since this directory is only
accessible by root
While ref_tracker_dir_init() is generally called from a context where
sleeping is OK, ref_tracker_dir_exit() can be called from anywhere.
Thus, dentry cleanup must be handled asynchronously.
Add a new global xarray that has entries with the ref_tracker_dir
pointer as the index and the corresponding debugfs dentry pointer as the
value. Instead of removing the debugfs dentry, have
ref_tracker_dir_exit() set a mark on the xarray entry and schedule a
workqueue job. The workqueue job then walks the xarray looking for
marked entries, and removes their xarray entries and the debugfs
dentries.
Because of this, the debugfs dentry can outlive the corresponding
ref_tracker_dir. Have ref_tracker_debugfs_show() take extra care to
ensure that it's safe to dereference the dir pointer before using it.

In a later patch, we'll be adding a 3rd mechanism for outputting
ref_tracker info via seq_file. Instead of a conditional, have the caller
set a pointer to an output function in struct ostream. As part of this,
the log prefix must be explicitly passed in, as it's too late for the
pr_fmt macro.

Add a new "ref_tracker" directory in debugfs. Each individual refcount
tracker can register files under there to display info about
currently-held references.

====================
netpoll: Code organization improvements
The netpoll_setup() function has grown complex over time, mixing
different error handling and concerns like carrier waiting, IPv4 address
retrieval, and IPv6 address retrieval all within a single function,
which is huge (127 LoC).
This patch series refactors the netpoll_setup() function to improve code
organization and readability by extracting logical blocks into dedicated
helper functions. netpoll_setup() length is reduced to 72 LoC.
This series breaks down these responsibilities into focused helper
functions.
The changes are purely structural with no functional modifications.
This changes were tested with the netconsole tests and the netpoll
selftest (WIP)[1]
