Move specific at8031 WOL enable/disable to dedicated function to make at803x_set_wol more generic. This is needed in preparation for PHY driver split as qca8081 share the same function to toggle WOL settings. In this new implementation WOL module in at8031 is enabled after the generic interrupt is setup. This should not cause any problem as the WOL_INT has a separate implementation and only relay on MAC bits. Signed-off-by:

The function and the struct related to hw_stats were specific to qca83xx PHY but were called following the convention in the driver of calling everything with at803x prefix. To better organize the code, rename these function a more specific name to better describe that they are specific to 83xx PHY family. Signed-off-by:

Mode supported is currently reported to the user exactly the same, as the current mode. That's because mode changing is not implemented. Remove the leftover mode_supported() op and use mode_get() to fill up the supported mode exposed to user. One, if even, mode changing is going to be introduced, this could be very easily taken back. In the meantime, prevent drivers form implementing this in wrong way (as for example recent netdevsim implementation attempt intended to do). Signed-off-by:

In a busy network, especially with flow control enabled, we may experience timestamp query failures fairly regularly. After a while, dmesg may be flooded with timestamp query failure error messages. Silence the error message from the low level hwrm function that sends the firmware message. Change netdev_err() to netdev_WARN_ONCE() if this FW call ever fails. Signed-off-by:

We don't have to close and open the nic to make sure we have valid rx timestamps. Once we have the timestamp filter applied to the HW and the timestamp_fld_format bit is cleared in the rx completion and the timestamp is non-zero, we can be sure that rx timestamp is valid data. Skip close/open when we set any timestamp filter. Reviewed-by:

rx_filter_miss counter is newly added to the rx_port_stats_ext stats structure for newer chips. Newer firmware will return the structure size that includes this counter. Add this entry to the bnxt_port_stats_ext_arr array and the ethtool -S code will pick up this counter if it is supported. Signed-off-by:

On the new P7 chips, TPA for tunnel packets can be independently enabled for each VNIC. The default TPA configuration should not include UDP tunnels because the UDP ports for these tunnels are not known yet. The chip should not aggregate these UDP tunneled packets using default UDP ports until the ports are known. Add a new function bnxt_hwrm_vnic_update_tunl_tpa() to enable VXLAN and Geneve TPA if the corresponding UDP ports are known. Reviewed-by:

Add VXLAN GPE tunnel type handling to the .set_port() and .unset_port() functions. .ndo_features_check() is also enhanced to support VXLAN GPE which may encapsulate inner IP packets instead of ethernet packets.

TX coalesced completions are supported on newer chips to provide one TX completion record for multiple TX packets up to the sq_cons_idx in the completion record. This method saves PCIe bandwidth by reducing the number of TX completions. Only very minor changes are now required to support this mode with the new framework that handles TX completions based on the consumer indices. Signed-off-by:

If xmit_more condition is true, the driver may set the TX_BD_FLAGS_NO_CMPL flag. If after this packet, the TX ring can no longer hold a packet with maximum fragments, we will stop the TX queue. When this happens, we must clear the TX_BD_FLAGS_NO_CMPL flag on the last packet or there will be no completion and cause TX timeout.

Two spots were missed when modifying the TX ring indexing logic. The use of unmasked TX index in bnxt_tx_int() will cause unnecessary __bnxt_tx_int() calls.

_bnxt_get_max_rings() that is invoked in bnxt_check_rings() already accounts for the AGG ring(s) and gives a max value based on that. Increasing for AGG rings before calling _bnxt_get_max_rings() will result in checking for twice the number of rings than required and it can fail. Fix it by adjusting for AGG rings after calling _bnxt_get_max_rings(). Fixes: f5b29c6a ("bnxt_en: Add helper to get the number of CP rings required for TX rings") Signed-off-by:

The recent commit to trim the RX and TX rings on P5 chips by assigning each with max CP rings divided by 2 is not correct. Max CP rings divided by 2 may be bigger than the original RX or TX and would lead to failure. In other words, we may be checking for increased RX/TX rings than required and it may fail. Fix it by calling __bnxt_trim_rings() instead that would properly trim RX and TX without the possibility of increasing their values.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect new_bus->id to be NUL-terminated but not NUL-padded based on its prior assignment through snprintf: | snprintf(new_bus->id, MII_BUS_ID_SIZE, "gpio-%x", bus_id); Due to this, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. We can also use sizeof() instead of a length macro as this more closely ties the maximum buffer size to the destination buffer. Do this for two instances.

The Lantiq PEF2256 is a framer and line interface component designed to fulfill all required interfacing between an analog E1/T1/J1 line and the digital PCM system highway/H.100 bus. This kind of component can be found in old telecommunication system. It was used to digital transmission of many simultaneous telephone calls by time-division multiplexing. Also using HDLC protocol, WAN networks can be reached through the framer. This pinmux support handles the pin muxing part (pins RP(A..D) and pins XP(A..D)) of the PEF2256. Signed-off-by:

A framer is a component in charge of an E1/T1 line interface. Connected usually to a TDM bus, it converts TDM frames to/from E1/T1 frames. It also provides information related to the E1/T1 line. The framer framework provides a set of APIs for the framer drivers (framer provider) to create/destroy a framer and APIs for the framer users (framer consumer) to obtain a reference to the framer, and use the framer. This basic implementation provides a framer abstraction for: - power on/off the framer - get the framer status (line state) - be notified on framer status changes - get/set the framer configuration Signed-off-by:

When compiling with gcc version 14.0.0 20231129 (experimental) and CONFIG_FORTIFY_SOURCE=y, I've noticed the following warning: ...

[-Wattribute-warning] 588 | __read_overflow2_field(q_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ... This call to 'memcpy()' is interpreted as an attempt to copy TX_OVERHEAD (which is 8) bytes from 4-byte 'sop' field of 'struct tx_pkt_info' and thus overread warning is issued.

Linus Walleij says: ==================== net: dsa: realtek: Two RTL8366RB fixes These minor fixes were found while digging into other issues: a weirdly named variable and bogus MTU handling. Fix it up. Signed-off-by:
Paolo Abeni <pabeni@redhat.com>

Linus Walleij authored
The MTU callbacks are in layer 1 size, so for example 1500 bytes is a normal setting. Cache this size, and only add the layer 2 framing right before choosing the setting. On the CPU port this will however include the DSA tag since this is transmitted from the parent ethernet interface! Add the layer 2 overhead such as ethernet and VLAN framing and FCS before selecting the size in the register. This will make the code easier to understand. The rtl8366rb_max_mtu() callback returns a bogus MTU just subtracting the CPU tag, which is the only thing we should NOT subtract. Return the correct layer 1 max MTU after removing headers and checksum. Signed-off-by:

The driver is using iowriteXX()/ioreadXX() APIs which are LE IO accessors simplified as 1. Convert given value _from_ CPU _to_ LE 2. Write it to the device as is The dev_addr is a byte stream, but because the driver uses 16-bit IO accessors, it wants to perform double conversion on BE CPUs, but it took it wrong, as it effectivelly does two times _from_ CPU _to_ LE. What it has to do is to consider dev_addr as an array of LE16 and hence do _from_ LE _to_ CPU conversion, followed by implied _from_ CPU _to_ LE in the iowrite16(). To achieve that, use get_unaligned_le16(). This will make it correct and allows to avoid sparse warning as reported by LKP. Reported-by:
