* net: phy: fixed-phy: Drop GPIO from fixed_phy_add()Linus Walleij2019-02-056-35/+65
| | | | | | | | | | | | | | | | | | | | | | All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the RX checksum offload. This is enabled by default and may be disabled and re-enabled using 'ethtool': # ethtool -K eth0 rx off # ethtool -K eth0 rx on Some Ether MACs provide a simple checksumming scheme which appears to be completely compatible with CHECKSUM_COMPLETE: sum of all packet data after the L2 header is appended to packet data; this may be trivially read by the driver and used to update the skb accordingly. The same checksumming scheme is implemented in the EtherAVB MACs and now supported by the 'ravb' driver. In terms of performance, throughput is close to gigabit line rate with the RX checksum offload both enabled and disabled. The 'perf' output, however, appears to indicate that significantly less time is spent in do_csum() -- this is as expected.

* sh_eth: rename sh_eth_cpu_data::hw_checksumSergei Shtylyov2019-02-042-8/+8
| | | | | | | | | | | | Commit 62e04b7e0e3c ("sh_eth: rename 'sh_eth_cpu_data::hw_crc'") renamed the field to 'hw_checksum' for the Ether DMAC "intelligent checksum", however some Ether MACs implement a simpler checksumming scheme, so that name now seems misleading. Rename that field to 'csmr' as the "intelligent checksum" is always controlled by the CSMR register.

To be able to use the paged version of e.g. phy_write() we need a PHY driver with the read_page and write_page callbacks implemented.

Even though compiler is not supposed to generate such instructions and manual written assembly is unlikely to have them, but they are legal instructions and have defined behavior. This patch correct existing shifts code-gen to make sure they do nothing when shift amount is zero except when the instruction is ALU32 for which high bits need to be cleared. For shift amount bigger than type size, already, NFP JIT back-end errors out for immediate shift and only low 5 bits will be taken into account for indirect shift which is the same as x86.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
