Clear the RGMII_LINK bit upon detecting link down to be consistent with setting the bit upon link up. We also move the clearing of the out-of-band disable to the runtime initialization rather than for each link up/down transition.

2022-11-08bnxt_en: Add a non-real time mode to access NIC clockPavan Chebbi
When using a PHC that is shared between multiple hosts, in order to achieve consistent timestamps across all hosts, we need to isolate the PHC from any host making frequency adjustments. This patch adds a non-real time mode for this purpose. The implementation is based on a free running NIC hardware timer which is used as the timestamper time-base. Each host implements individual adjustments to a local timecounter based on the NIC free running timer.

Hardware is unable to realize all legal firmware interface state values for hash_type. For example, if 4-tuple TCP_IPV4 hash is enabled, 4-tuple UDP_IPV4 hash must also be enabled. By providing the bits the user intended to change instead of the possible illegal intermediate states, the firmware is able to make better compromises when deciding which bits to ignore. With this new mechansim, we can now report the actual configured hash back to the user. Add bnxt_hwrm_update_rss_hash_cfg() to report the actual hash after user configuration.

2022-11-08ethtool: linkstate: add a statistic for PHY down eventsJakub Kicinski
The previous attempt to augment carrier_down (see Link) was not met with much enthusiasm so let's do the simple thing of exposing what some devices already maintain. Add a common ethtool statistic for link going down. Currently users have to maintain per-driver mapping to extract the right stat from the vendor-specific ethtool -S stats. carrier_down does not fit the bill because it counts a lot of software related false positives. Add the statistic to the extended link state API to steer vendors towards implementing all of it. Implement for bnxt and all Linux-controlled PHYs. mlx5 and (possibly) enic also have a counter for this but I leave the implementation to their maintainers.

RX code can be more efficient with the build_skb(). Allocating actual SKB around eth packet buffer - right before passing it up - results in a better cache usage. Without RPS (echo 0 > rps_cpus) BCM4908 NAT masq performance "jumps" between two speeds: ~900 Mbps and 940 Mbps (it's a 4 CPUs SoC). This change bumps the lower speed from 905 Mb/s to 918 Mb/s (tested using single stream iperf 2.0.5 traffic). There are more optimizations to consider. One obvious to try is GRO however as BCM4908 doesn't do hw csum is may actually lower performance. Sometimes.

The intent of this pull is to clean up the way callers fetch random integers. The current rules for doing this right are: - If you want a secure or an insecure random u64, use get_random_u64() - If you want a secure or an insecure random u32, use get_random_u32() The old function prandom_u32() has been deprecated for a while now and is just a wrapper around get_random_u32(). Same for get_random_int(). - If you want a secure or an insecure random u16, use get_random_u16() - If you want a secure or an insecure random u8, use get_random_u8() - If you want secure or insecure random bytes, use get_random_bytes(). The old function prandom_bytes() has been deprecated for a while now and has long been a wrapper around get_random_bytes() - If you want a non-uniform random u32, u16, or u8 bounded by a certain open interval maximum, use prandom_u32_max() I say "non-uniform", because it doesn't do any rejection sampling or divisions. Hence, it stays within the prandom_*() namespace, not the get_random_*() namespace. I'm currently investigating a "uniform" function for 6.2. We'll see what comes of that. By applying these rules uniformly, we get several benefits: - By using prandom_u32_max() with an upper-bound that the compiler can prove at compile-time is ≤65536 or ≤256, internally get_random_u16() or get_random_u8() is used, which wastes fewer batched random bytes, and hence has higher throughput. - By using prandom_u32_max() instead of %, when the upper-bound is not a constant, division is still avoided, because prandom_u32_max() uses a faster multiplication-based trick instead. - By using get_random_u16() or get_random_u8() in cases where the return value is intended to indeed be a u16 or a u8, we waste fewer batched random bytes, and hence have higher throughput. This series was originally done by hand while I was on an airplane without Internet. Later, Kees and I worked on retroactively figuring out what could be done with Coccinelle and what had to be done manually, and then we split things up based on that. So while this touches a lot of files, the actual amount of code that's hand fiddled is comfortably small" * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: prandom: remove unused functions treewide: use get_random_bytes() when possible treewide: use get_random_u32() when possible treewide: use get_random_{u8,u16}() when possible, part 2 treewide: use get_random_{u8,u16}() when possible, part 1 treewide: use prandom_u32_max() when possible, part 2 treewide: use prandom_u32_max() when possible, part 1

But when "pad + len > fp->rx_buf_size" is true, bnx2x_tpa_stop() returns without releasing the new_data, which will lead to a memory leak.

2022-09-22bnxt_en: replace reset with config timestampsVadim Fedorenko
Any change to the hardware timestamps configuration triggers nic restart, which breaks transmition and reception of network packets for a while. But there is no need to fully restart the device because while configuring hardware timestamps. The code for changing configuration runs after all of the initialisation, when the NIC is actually up and running. This patch changes the code that ioctl will only update configuration registers and will not trigger carrier status change, but in case of timestamps for all rx packetes it fallbacks to close()/open() sequnce because of synchronization issues in the hardware.
