2018-12-18net: phy: print stack trace in phy_errorHeiner Kallweit1-0/+2
So far phy_error() silently stops the PHY state machine. If the network driver doesn't inform about a MDIO error then the user may wonder why his network is down.

2018-12-18net: phy: improve phy state checkingHeiner Kallweit1-13/+21
Add helpers phy_is_started() and __phy_is_started() to avoid open-coded checks whether PHY has been started. To make the check easier move PHY_HALTED before PHY_UP in enum phy_state. Further improvements: phy_start_aneg(): Return -EBUSY and print warning if function is called from a non-started state (DOWN, READY, HALTED). Better check because function is exported and drivers may use it incorrectly. phy_interrupt(): Return IRQ_NONE also if state is DOWN or READY. We should never receive an interrupt in one of these states, but better play safe. phy_stop(): Just return and print a warning if PHY is in a non-started state. This warning should help to identify drivers with unbalanced calls to phy_start() / phy_stop(). phy_state_machine(): Schedule state machine run only if PHY is in a started state. E.g. if state is READY we don't need the state machine, it will be started by phy_start(). v2: - don't use __func__ within phy_warn_state v3: - use WARN() instead of printing error message to facilitate debugging Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2018-12-18net: fec: remove workaround to restart phylib state machine on MDIO timeoutHeiner Kallweit2-13/+0
There's a workaround to restart the phylib state machine in case of a MDIO access timeout. Seems it was introduced to deal with the consequences of a too small MDIO timeout. See also commit message of c3b084c24c8a ("net: fec: Adjust ENET MDIO timeouts") which increased the timeout value later. Due to the later timeout value fix it seems to be safe to remove the workaround. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-12-18net: hns3: fix a SSU buffer checking bugYunsheng Lin1-2/+3
When caculating the SSU buffer, it first allocate tx and rx private buffer, then the remaining buffer is for rx shared buffer. The remaining buffer size should be at least bigger than or equal to the shared_std, which is the minimum shared buffer size required by the driver, but currently if the remaining buffer size is equal to the shared_std, it returns failure, which causes SSU buffer allocation failure problem. This patch fixes this problem by rounding up shared_std before checking the the remaining buffer size bigger than or equal to the shared_std.

2018-12-17nfp: flower: fix cb_ident duplicate in indirect block registerJohn Hurley1-10/+11
Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the netdev we were interested in receiving updates on. This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

2018-12-16mlxsw: spectrum_acl: Add Bloom filter handlingNir Dotan2-0/+219
Spectrum-2 HW uses Bloom filter in order to skip lookups on specific eRPs. It uses crc-16-Msbit-first calculation over a specific layout of a rule's key fields combined with eRP ID as well as region ID. Per potential lookup, iff the Bloom filter entry of the calculated index is empty, then the lookup can be skipped. Hence, the mlxsw driver should update the Bloom filter entry per each rule insertion or deletion when rules are part of an eRP. Add functions for adding and deleting entries in the Bloom filter. In order to do so also add crc-16 computation based on the specific Spectrum-2 polynomial and a function for encoding the crc-16 input in the manner dictated by HW implementation.

Saeed Mahameed says: ==================== mlx5e-updates-2018-12-14 (VF Lag) From Aviv Heller, Subsequent patches introduce VF LAG, which provdies load-balancing and high-availability capabilities for VFs associated with different physical ports of the same Connect-X card. This series consists of the following: - mlx5 devcom, driver infrastructure that facilitates operations that involve both core devices (physical functions) of the same card, to synchronize and communicate between two driver instances of the same card. - Infrastructure for TC rule duplication. - Changes to LAG logic to enable its use when SR-IOV is enabled - PFs in switchdev mode is the only mode currently supported. ==================== Signed-off-by: David S.
