2017-11-14mailbox: mailbox-test: don't rely on rx_buffer content to signal data readySudeep Holla
Currently we rely on the first byte of the Rx buffer to check if there's any data available to be read. If the first byte of the received buffer is zero (i.e. null character), then we fail to signal that data is available even when it's available. Instead introduce a boolean variable to track the data availability and update it in the channel receive callback as ready and clear it when the data is read.

2017-11-14mailbox: reset txdone_method TXDONE_BY_POLL if client knows_txdoneSudeep Holla
Currently the mailbox framework sets txdone_method to TXDONE_BY_POLL if the controller sets txdone_by_poll. However some clients can have a mechanism to do TXDONE_BY_ACK which they can specify by knows_txdone. However, we endup setting both TXDONE_BY_POLL and TXDONE_BY_ACK in that case. In such scenario, we may end up with below warnings as the tx ticker is run both by mailbox framework and the client.

2017-11-14net: stmmac: fix LPI transitioning for dwmac4Niklas Cassel
The LPI transitioning logic in stmmac_main uses priv->tx_path_in_lpi_mode to enter/exit LPI. However, priv->tx_path_in_lpi_mode is assigned using the return value from host_irq_status(). So for dwmac4, priv->tx_path_in_lpi_mode was always false, so stmmac_tx_clean() would always try to put us in eee mode, and stmmac_xmit() would never take us out of eee mode. To fix this, make host_irq_status() read and return the LPI irq status also for dwmac4. This also increments the existing LPI counters, so that ethtool --statistics shows LPI transitions also for dwmac4. For dwmac1000, irqs are enabled/disabled using the register named "Interrupt Mask Register", and thus setting a bit disables that specific irq. For dwmac4 the matching register is named "MAC_Interrupt_Enable", and thus setting a bit enables that specific irq. Looking at dwmac1000_core.c, the irqs that are always enabled are: LPI and PMT. Looking at dwmac4_core.c, the irqs that are always enabled are: PMT. To be able to read the LPI irq status, we need to enable the LPI irq also for dwmac4.

2017-11-14net: mvneta: fix handling of the Tx descriptor counterSimon Guinot
The mvneta controller provides a 8-bit register to update the pending Tx descriptor counter. Then, a maximum of 255 Tx descriptors can be added at once. In the current code the mvneta_txq_pend_desc_add function assumes the caller takes care of this limit. But it is not the case. In some situations (xmit_more flag), more than 255 descriptors are added. When this happens, the Tx descriptor counter register is updated with a wrong value, which breaks the whole Tx queue management. This patch fixes the issue by allowing the mvneta_txq_pend_desc_add function to process more than 255 Tx descriptors.

After commit b94d22d94ad22 "ARM64: dts: meson-gx: add external PHY interrupt on some platforms" ethernet stopped working on my Odroid-C2 which has a RTL8211F phy. It turned out that no interrupts were triggered. Further analysis showed the register INER can't be altered on page 0. Because register INSR needs to be accessed via page 0xa43 I assumed that register INER needs to be accessed via some page too. Some brute force check resulted in page 0xa42 being the right one. With this patch the phy is working properly in interrupt mode.

Rasmus Villemoes says: ==================== net: core: devname allocation cleanups It's somewhat confusing to have both dev_alloc_name and dev_get_valid_name. I can't see why the former is less strict than the latter, so make them (or rather dev_alloc_name_ns and dev_get_valid_name) equivalent, hardening dev_alloc_name() a little. Obvious follow-up patches would be to only export one function, and make dev_alloc_name a static inline wrapper for that (whichever name is chosen for the exported interface). But maybe there is a good reason the two exported interfaces do different checking, so I'll refrain from including the trivial but tree-wide renaming in this series. ==================== Signed-off-by: David S.
