Oleksij Rempel says: ==================== provide generic net selftest support changes v3: - make more granular tests - enable loopback for all PHYs by default - fix allmodconfig build errors - poll for link status update after switching to the loopback mode changes v2: - make generic selftests available for all networking devices. - make use of net_selftest* on FEC, ag71xx and all DSA switches. - add loopback support on more PHYs. This patch set provides diagnostic capabilities for some iMX, ag71xx or any DSA based devices. For proper functionality, PHY loopback support is needed. So far there is only initial infrastructure with basic tests. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Most of generic selftest should be able to work with probably all ethernet controllers. The DSA switches are not exception, so enable it by default at least for DSA. This patch was tested with SJA1105 and AR9331. Signed-off-by:

In case of loopback, in most cases we need to disable autoneg support and force some speed configuration. Otherwise, depending on currently active auto negotiated link speed, the loopback may or may not work. This patch was tested with following PHYs: TJA1102, KSZ8081, KSZ9031, AT8035, AR9331.

The generic loopback is really generic and is defined by the 802.3 standard, we should just mandate that drivers implement a custom loopback if the generic one cannot work. Suggested-by:

Thomas Bogendoerfer says: ==================== net: Korina improvements While converting Mikrotik RB532 support to use device tree I stumbled over the korina ethernet driver, which used way too many MIPS specific hacks. This series cleans this all up and adds support for device tree.

Vladimir Oltean says: ==================== Flow control for NXP ENETC This patch series contains logic for enabling the lossless mode on the RX rings of the ENETC, and the PAUSE thresholds on the internal FIFO memory. During testing it was found that, with the default FIFO configuration, a sender which isn't persuaded by our PAUSE frames and keeps sending will cause some MAC RX frame errors. To mitigate this, we need to ensure that the FIFO never runs completely full, so we need to fix up a setting that was supposed to be configured well out of reset. Unfortunately this requires the addition of a new mini-driver. ==================== Signed-off-by: -
Vladimir Oltean authored
In the ENETC receive path, a frame received by the MAC is first stored in a 256KB 'FIFO' memory, then transferred to DRAM when enqueuing it to the RX ring. The FIFO is a shared resource for all ENETC ports, but every port keeps track of its own memory utilization, on RX and on TX. There is a setting for RX rings through which they can either operate in 'lossy' mode (where the lack of a free buffer causes an immediate discard of the frame) or in 'lossless' mode (where the lack of a free buffer in the ring makes the frame stay longer in the FIFO). In turn, when the memory utilization of the FIFO exceeds a certain margin, the MAC can be configured to emit PAUSE frames. There is enough FIFO memory to buffer up to 3 MTU-sized frames per RX port while not jeopardizing the other use cases (jumbo frames), and also not consume bytes from the port TX allocations. Also, 3 MTU-sized frames worth of memory is enough to ensure zero loss for 64 byte packets at 1G line rate. Signed-off-by:
