2021-09-23atlantic: Fix issue in the pm resume flow.Sudarsana Reddy Kalluru1-2/+2
After fixing hibernation resume flow, another usecase was found which should be explicitly handled - resume when device is in "down" state. Invoke aq_nic_init jointly with aq_nic_start only if ndev was already up during suspend/hibernate. We still need to perform nic_deinit() if caller requests for it, to handle the freeze/resume scenarios. Fixes: 57f780f1c433 ("atlantic: Fix driver resume flow.")

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below. It has been hand modified to use 'dma_set_mask_and_coherent()' instead of 'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable. This is less verbose. A useless "!= 0" has also been removed in a test.

2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann1-1/+1
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

2021-02-11net: ethernet: aquantia: Handle error cleanup of start on openNathan Rossi1-1/+3
The aq_nic_start function can fail in a variety of cases which leaves the device in broken state. An example case where the start function fails is the request_threaded_irq which can be interrupted, resulting in a EINTR result. This can be manually triggered by bringing the link up (e.g. ip link set up) and triggering a SIGINT on the initiating process (e.g. Ctrl+C). This would put the device into a half configured state. Subsequently bringing the link up again would cause the napi_enable to BUG. In order to correctly clean up the failed attempt to start a device call aq_nic_stop.

2020-11-24aquantia: Remove the build_skb pathLincoln Ramsay1-74/+52
When performing IPv6 forwarding, there is an expectation that SKBs will have some headroom. When forwarding a packet from the aquantia driver, this does not always happen, triggering a kernel warning. aq_ring.c has this code (edited slightly for brevity): if (buff->is_eop && buff->len <= AQ_CFG_RX_FRAME_MAX - AQ_SKB_ALIGN) { skb = build_skb(aq_buf_vaddr(&buff->rxdata), AQ_CFG_RX_FRAME_MAX); } else { skb = napi_alloc_skb(napi, AQ_CFG_RX_HDR_SIZE); There is a significant difference between the SKB produced by these 2 code paths. When napi_alloc_skb creates an SKB, there is a certain amount of headroom reserved. However, this is not done in the build_skb codepath. As the hardware buffer that build_skb is built around does not handle the presence of the SKB header, this code path is being removed and the napi_alloc_skb path will always be used. This code path does have to copy the packet header into the SKB, but it adds the packet data as a frag.

The UDP reuseport conflict was a little bit tricky. The net-next code, via bpf-next, extracted the reuseport handling into a helper so that the BPF sk lookup code could invoke it. At the same time, the logic for reuseport handling of unconnected sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace which changed the logic to carry on the reuseport result into the rest of the lookup loop if we do not return immediately. This requires moving the reuseport_has_conns() logic into the callers. While we are here, get rid of inline directives as they do not belong in foo.c files.

This is necessary for per-ring stats, because they are updated by the driver directly, so there is a possibility for a partial read. Other stats require no additional protection, e.g.: * all MACSec stats are fetched directly from HW (under semaphore); * nic/ndev stats (aq_stats_s) are fetched directly from FW (under mutex).

This patch replaces addition assignment operator with a simple assignment in aq_vec_get_stats() and aq_vec_get_sw_stats(), because it is sufficient in both cases and this change simplifies the introduction of u64_stats_update_* in these functions.

2020-07-17net: atlantic: add support for FW 4.xDmitry Bogdanov4-15/+58
This patch adds support for FW 4.x, which is about to get into the production for some products. 4.x is mostly compatible with 3.x, save for soft reset, which requires the acquisition of 2 additional semaphores. Other differences (e.g. absence of PTP support) are handled via capabilities. Note: 4.x targets specific products only. 3.x is still the main firmware branch, which should be used by most users (at least for now).

2020-07-17net: atlantic: disable PTP on AQC111, AQC112Nikita Danilov7-10/+68
This patch disables PTP on AQC111 and AQC112 due to a known HW issue, which can cause datapath issues. Ideally PTP block should have been disabled via PHY provisioning, but unfortunately many units have been shipped with enabled PTP block. Thus, we have to work around this in the driver.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'.

2020-06-26net: atlantic: put ptp code under IS_REACHABLE checkIgor Russkikh4-6/+27
A1 requires additional processing for both egress and ingress to support PTP. And it makes sense to get rid of this processing altogether (via ifdef), if PTP clock is disabled globally. This patch puts the PTP code under the corresponding IS_REACHABLE check.

All these helper macros assume the length to be aligned (multiple of 4). If it's not aligned, then there might be issues, e.g. stack corruption.
