Add a boolean property which indicates if the PHY has had any fixup routine ran on it. We are later going to use that boolean to expose it as a sysfs property to help troubleshooting. Signed-off-by:

Expose the PHY device interface mode through sysfs since this is an useful piece of information for knowing how the attached networking device will have configured its transmit/receive path. Signed-off-by:

Florian Fainelli authored
of_get_phy_mode() uses a local array to map phy_interface_t values from include/linux/net/phy.h to a string which is read from the 'phy-mode' or 'phy-connection-type' property. In preparation for exposing the PHY interface mode through sysfs, perform the following: - mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such that it is right below the phy_interface_t enum - make it a static inline function returning the string such that we can use it by just including include/linux/net/phy.h - add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in of_get_phy_mode() Signed-off-by:

The comments above phy_{clear,config}_interrupt used the word "on" instead of "or", when talking about the return values of the functions, fix these two typos. Signed-off-by: -

Some PHYs out there can be very quirky with respect to how they would report the auto-negotiation is completed. Allow drivers to override the generic aneg_done() implementation by providing their own. Since not all drivers have been updated yet to use genphy_aneg_done() as aneg_done() callback, we explicitely check that this callback is valid before calling into it. Signed-off-by:

In preparation for allowing PHY drivers to potentially override their auto-negotiation done callback, move the contents of phy_aneg_done() to genphy_aneg_done() since that function really is the generic implementation based on the BMSR_ANEGCOMPLETE status. Signed-off-by:

Use a convenience function: phy_speed_to_str() which will display human readable speeds. Suggested-by:

Update phy_print_status() to also display the PHY device pause settings (rx/tx or off). Suggested-by:
-
Florian Fainelli authored
phy_print_status() currently uses dev_name(&phydev->dev) which will usually result in printing something along those lines for Device Tree aware drivers: libphy: f0b60000.etherne:0a - Link is Down libphy: f0ba0000.etherne:00 - Link is Up - 1000/Full This is not terribly useful for network administrators or users since we expect a network interface name to be able to correlate link events with interfaces. Update phy_print_status() to use netdev_info() with phydev->attached_dev which is the backing network device for our PHY device. The leading dash is removed since netdev_info() prefixes the messages with "<interface>: " already. Signed-off-by:

Shradha Shah says: ==================== Cleanup patches for the SFC driver This patch set consists of some cleanup and housekeeping patches for the sfc driver. These patches help to reduce the differences between the in- tree and out-of-tree driver. Ben Hutchings (12): sfc: Cache skb->data in local variable in efx_ptp_rx() sfc: Rewrite adjustment of PPS event in a clearer way sfc: Replace TSOH_OFFSET with the equivalent NET_IP_ALIGN sfc: Rename 'use_options' variable in tso_start() to clearer 'use_opt_desc' sfc: Remove unused definitions of EF10 user-mode DMA descriptors sfc: Correct comment about number of TX queues used on EF10 sfc: Preserve rx_frm_trunc counters when resizing DMA rings sfc: Use canonical pointer type for MAC address in efx_set_mac_address() sfc: Update product naming sfc: Cosmetic changes to self-test from the out-of-tree driver sfc: Fail self-test with -EBUSY, not -EIO, if the device is busy sfc: Add/remove blank lines to taste Laurence Evans (1): sfc: Removed adhoc scheme to rate limit PTP event queue overflow message ==================== Signed-off-by: -

Remove trailing blank lines in several files. Use only one blank line between functions. Add a blank line as a separator in a few places. Signed-off-by:

We allocate efx_channel structures with kzalloc() so we don't need to zero-initialise individual fields in efx_probe_channel(). Further, this function will be called again during DMA ring resizing and we should not reset any statistics then. Signed-off-by:

EF10 implements option descriptors to switch TX checksum offload on and off between packets. We could therefore use a single hardware TX queue per kernel TX queue, although we don't yet. Signed-off-by:

If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is defined then NET_IP_ALIGN will be defined as 0, so this macro is redundant. Signed-off-by:

There is substantial latency in generation and handling of PPS events from the NIC, which we have to correct for before passing a host timestamp to the PPS subsystem. We compare clocks with the MC, giving us two offsets to subtract from the timestamp generated by pps_get_ts(): (a) Time from the last good sync (where we got host and NIC timestamps for nearly the same instant) to the time we called pps_get_ts() (b) Time from NIC top of second to the last good sync We currently calculate (a) + (b) in a quite confusing way. Instead, calculate (a) completely, then add (b) to it. Signed-off-by: -

Ben Hutchings says: ==================== ethtool: Improve documentation This series converts most comments in <linux/ethtool.h> into kernel-doc format, and expands them to describe the semantics as well as I understand them. It also fixes some kernel-doc formatting errors. I started on this at Solarflare, but they graciously allowed me to take it away and finish it off. ==================== Signed-off-by: -

A colon almost unavoidably starts a new section. The script should be changed to provide a way to avoid this, but for now reword the comments to avoid using colons. Signed-off-by:

Various ethtool command structures are declared with zero-length array at the end which are intended to be variable-length in userland (relying on lack of compiler bounds checking). However, in the kernel the structure and array are always allocated and passed to driver operations separately. Make that explicit. Signed-off-by:

Convert the inline comments to kernel-doc format. Explicitly specify that non-zero autoneg is an error if link autonegotiation is disabled. Specify that pause capabilities should be advertised dependent on link autonegotiation, not the autoneg flag here. There is no way to opt-out of pause frame autonegotiation, and this improves behaviour when the link partner is configured to follow pause frame autonegotiation and our interface is not.

Replace the inline comments (and some others below) with a full explanation of the semantics, in kernel-doc format. Specify which strings may be empty. Document the relationship with other commands. Replace the 'deprecation' of some fields with a proper explanation of the conversion to generalised string sets, as userland programs may not be able to assume that ETHTOOL_GSSET_INFO is available.

struct ethtool_cmd has very limited documentation; it contains several obscure or obsolete fields and several with non-obvious interpretation. Replace the inline comments (and some others below) with a full explanation of the semantics as well as I understand them, in kernel-doc format. Formally deprecate some fields that seem to be of historical use only. Extend the comment about 32/64-bit compatibility to cover all ethtool structures. Signed-off-by:
