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:

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:

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.

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:

When a device ndo_start_xmit() calls again dev_queue_xmit(), lockdep can complain because dev_queue_xmit() is re-entered and the spinlocks protecting tx queues share a common lockdep class.

The 9p-virtio transport does zero copy on things larger than 1024 bytes in size. It accomplishes this by returning the physical addresses of pages to the virtio-pci device. At present, the translation is usually a bit shift. That approach produces an invalid page address when we read/write to vmalloc buffers, such as those used for Linux kernel modules. Any attempt to load a Linux kernel module from 9p-virtio produces the following stack. [<ffffffff814878ce>] p9_virtio_zc_request+0x45e/0x510 [<ffffffff814814ed>] p9_client_zc_rpc.constprop.16+0xfd/0x4f0 [<ffffffff814839dd>] p9_client_read+0x15d/0x240 [<ffffffff811c8440>] v9fs_fid_readn+0x50/0xa0 [<ffffffff811c84a0>] v9fs_file_readn+0x10/0x20 [<ffffffff811c84e7>] v9fs_file_read+0x37/0x70 [<ffffffff8114e3fb>] vfs_read+0x9b/0x160 [<ffffffff81153571>] kernel_read+0x41/0x60 [<ffffffff810c83ab>] copy_module_from_fd.isra.34+0xfb/0x180 Subsequently, QEMU will die printing: qemu-system-x86_64: virtio: trying to map MMIO memory This patch enables 9p-virtio to correctly handle this case. This not only enables us to load Linux kernel modules off virtfs, but also enables ZFS file-based vdevs on virtfs to be used without killing QEMU. Special thanks to both Avi Kivity and Alexander Graf for their interpretation of QEMU backtraces. Without their guidence, tracking down this bug would have taken much longer. Also, special thanks to Linus Torvalds for his insightful explanation of why this should use is_vmalloc_addr() instead of is_vmalloc_or_module_addr(): https://lkml.org/lkml/2014/2/8/272Signed-off-by:
