The existing documentation was not telling that one has to create a PPP channel and a PPP interface to get PPPoL2TP data offloading working. Also, tunnel switching was not mentioned, so that people were thinking it was not supported, while it actually is. Signed-off-by:

We want to re-organize the struct sock layout. The sk_peek_off field location is problematic, as most protocols want it in the RX read area, while UDP wants it on a cacheline different from sk_receive_queue. Create a local (inside udp_sock) copy of the 'peek offset is enabled' flag and place it inside the same cacheline of reader_queue. Check such flag before reading sk_peek_off. This will save potential false sharing and cache misses in the fast-path. Tested under UDP flood with small packets. The struct sock layout update causes a 4% performance drop, and this patch restores completely the original tput. Signed-off-by:

As soon as that provider is loaded however, the PHY continues to probe, tries to disable the interrupts, and this causes a MDIO transaction. That MDIO transaction requires I/O register accesses within the GENET's larger block, and since its clocks are turned off, the CPU gets a bus error signaled as a System Error. The patch series takes the simplest approach of keeping the clocks enabled just for the duration of the I/O accesses. This is also beneficial to other drivers like bcmasp2 which make use of the same MDIO controller driver.

GENET has historically had to create a MDIO platform device for its controller and pass some auxiliary data to it, like a MDIO completion callback. Now we also pass the "main" clock to allow for the MDIO bus controller to manage that clock adequately around I/O accesses. Reviewed-by:

Florian Fainelli authored
Up until now we have managed not to have the mdio-bcm-unimac manage its clock except during probe and suspend/resume. This works most of the time, except where it does not. With a fully modular build, we can get into a situation whereby the GENET driver is fully registered, and so is the mdio-bcm-unimac driver, however the Ethernet PHY driver is not yet, because it depends on a resource that is not yet available (e.g.: GPIO provider). In that state, the network device is not usable yet, and so to conserve power, the GENET driver will have turned off its "main" clock which feeds its MDIO controller. When the PHY driver finally probes however, we make an access to the PHY registers to e.g.: disable interrupts, and this causes a bus error within the MDIO controller space because the MDIO controller clock(s) are turned off. To remedy that, we manage the clock around all of the I/O accesses to the hardware which are done exclusively during read, write and clock divider configuration. This ensures that the register space is accessible, and this also ensures that there are not unnecessarily elevated reference counts keeping the clocks active when the network device is administratively turned off. It would be the case with the previous way of managing the clock. Reviewed-by:

With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now.
