Unfortunately the frame format is not exactly identical between SPI and UART. In case of SPI there is an additional HW length at the beginning. So store the initial state to make the decoding state machine more flexible and easy to extend for UART support. Signed-off-by: NStefan Wahren <stefan.wahren@i2se.com> Signed-off-by: NDavid S.

As preparation for the upcoming UART driver we need a module which contains common functions for both interfaces. The module qca_framing is a good candidate but renaming to qca_7k_common would make it clear. Signed-off-by: NStefan Wahren <stefan.wahren@i2se.com> Signed-off-by: NDavid S.

Bogdan Purcareata says: ==================== net: phy: Support managed Cortina phys So far, the Cortina family phys (CS4340 in this particular case) are only supported in fixed link mode (via fixed_phy_register). The generic 10G phy driver does not work well with the phylib state machine, when the phy is registered via of_phy_connect. This prohibits the user from describing the phy nodes in the device tree. In order to support this scenario, and to properly describe the board device tree, add a minimal Cortina driver that reads the status from the right register. With the generic 10G C45 driver, the kernel will print messages like: [ 0.226521] mdio_bus 8b96000: Error while reading PHY16 reg at 1.6 [ 0.232780] mdio_bus 8b96000: Error while reading PHY16 reg at 1.5 v3 -> v4: - Add trademark info. - Minor documentation entry consistency nit. v2 -> v3: - Add documentation entry. v1 -> v2: - Change approach for getting the phy_id from hacking get_phy_c45_ids to describing the device in the device tree via ethernet-phy-id. More patch version changes per individual patches. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add basic support for Cortina PHY drivers. Support only CS4340 for now. The phys are not compatible with IEEE 802.3 clause 22/45 registers. Implement proper read_status support. The generic 10G phy driver causes bus register access errors. The driver should be described using the "ethernet-phy-id" device tree compatible.

Yuval Mintz says: ==================== qed: DCBx and Attentions series The series contains 2 major components [& some odd bits]: - The first 3 patches are DCBx-related, containg missing bits in the implementation, correcting existing API and removing code no longer necessary. - Most of the remaining patches are interrupt/hw-attention related, adding some differeneces relating to QL41xxx and QL45xxx differences. While at it, they also remove a large chunk of unnecessary structure definitions.

The QL41xxx adapters' PCI allows a single configuration for the MSI-x table size of all child VFs of a given PF. The existing code wouldn't cause the management firmware to set that value, meaning the VFs would retain the default MSI-x table size. Introduce a new scheme so that whenever a VF is enabled, driver would set the number of MSI-x to be the maximum over the various VFs' needs.

Older firmware used by device didn't distinguish between RoCE and RoCE V2 from DCBx configuration perspective, and as a result we've used to take a the RoCE-related configuration and apply to it for both.

Jakub Kicinski says: ==================== nfp: pci core, hwmon, live mac addr change This series brings updates to core PCI code, SR-IOV, exposes firmware's capability to change MAC address at runtime and HWMON interfaces. The PCI code updates include resiliency improvement in conditions which are quite unusual, but still shouldn't make the driver oops. We also handle very large device memory operation more gracefully. A timeout is added to acquiring mutexes in device memory. Pablo provides a patch to expose to the stack the ability to change MAC addresses under traffic while David adds HWMON interface for reading device temperature and power consumption. Last three patches are minor improvements to the netdev code. v2: - add patch 1 - fix for devlink build; - fix build issue with the hwmon patch. ==================== Signed-off-by: NDavid S.

There is currently no timeout to the resource and lock acquiring loops. We printed warnings and depended on user sending a signal to the waiting process to stop the waiting. This doesn't work very well when wait happens out of a work queue. The simplest example of that is PCI probe. When user loads the module and card is in a broken state modprobe will wait forever and signals sent to it will not actually reach the probing thread. Make sure all wait loops have a time out. Set the upper wait time to 60 seconds to stay on the safe side. Signed-off-by: NJakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
