This patch constify the lowpan_nhc declarations. Since we drop the rb node datastructure there is no need for runtime manipulation of this structure. Signed-off-by:

Alexander Aring authored
This patch will remove the complete overengineered and overthinking rb data structure for looking up the nhc by nhcid. Instead we using the existing nhc next header array and iterate over it. It works now for 1 byte values only. However there are only 1 byte nhc id values currently supported and IANA also does not specify large than 1 byte values yet. If there are 2 byte values for nhc ids specified we can revisit this data structure and add support for it. Signed-off-by:

The keyword const makes no sense for scalar types inside the lowpan_nhc structure. Most compilers will ignore it so we remove the keyword from the scalar types. Signed-off-by:

Stefano Garzarella says: ==================== vsock/virtio: add support for device suspend/resume Vilas reported that virtio-vsock no longer worked properly after suspend/resume (echo mem >/sys/power/state). It was impossible to connect to the host and vice versa. Indeed, the support has never been implemented. This series implement .freeze and .restore callbacks of struct virtio_driver to support device suspend/resume. The first patch factors our the code to initialize and delete VQs. The second patch uses that code to support device suspend/resume. Signed-off-by:

Add virtio_vsock_vqs_init() and virtio_vsock_vqs_del() with the code that was in virtio_vsock_probe() and virtio_vsock_remove to initialize and delete VQs. These new functions will be used in the next commit to support device suspend/resume Signed-off-by:

The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action which enforced time-based access control per stream. A stream as seen by this switch is identified by {MAC DA, VID}. We use the standard forwarding selftest topology with 2 host interfaces and 2 switch interfaces. The host ports must require timestamping non-IP packets and supporting tc-etf offload, for isochron to work. The isochron program monitors network sync status (ptp4l, phc2sys) and deterministically transmits packets to the switch such that the tc-gate action either (a) always accepts them based on its schedule, or (b) always drops them. I tried to keep as much of the logic that isn't specific to the NXP LS1028A in a new tsn_lib.sh, for future reuse. This covers synchronization using ptp4l and phc2sys, and isochron. The cycle-time chosen for this selftest isn't particularly impressive (and the focus is the functionality of the switch), but I didn't really know what to do better, considering that it will mostly be run during debugging sessions, various kernel bloatware would be enabled, like lockdep, KASAN, etc, and we certainly can't run any races with those on. I tried to look through the kselftest framework for other real time applications and didn't really find any, so I'm not sure how better to prepare the environment in case we want to go for a lower cycle time. At the moment, the only thing the selftest is ensuring is that dynamic frequency scaling is disabled on the CPU that isochron runs on. It would probably be useful to have a blacklist of kernel config options (checked through zcat /proc/config.gz) and some cyclictest scripts to run beforehand, but I saw none of those.

Don't bother with linkinfo, it's referenced a lot and we take its size so it's awkward to move, plus it's small (6 elements). Reported-by:

Andrew Lunn says: ==================== Use MMD/C45 helpers MDIO busses can perform two sorts of bus transaction, defined in clause 22 and clause 45 of 802.3. This results in two register addresses spaces. The current driver structure for indicating if C22 or C45 should be used is messy, and many C22 only bus drivers will wrongly interpret a C45 transaction as a C22 transaction. This patchset is a preparation step to cleanup the situation. It converts MDIO bus users to make use of existing _mmd and _c45 helpers to perform accesses to C45 registers. This will later allow C45 and C22 to be kept separate. ==================== Link: https://lore.kernel.org/r/20220430173037.156823-1-andrew@lunn.chSigned-off-by:

VxLAN belongs to UDP-based encapsulation protocol. Inner TSO for VxLAN packet with udpcsum requires offloading of outer header csum. The device doesn't support outer header csum offload. However, inner TSO for VxLAN with udpcsum can still work with GSO_PARTIAL offload, which means outer udp csum computed by stack and inner tcp segmentation finished by hardware. Thus, the patch enable features "NETIF_F_GSO_UDP_TUNNEL_CSUM" and "NETIF_F_GSO_PARTIAL" and set gso_partial_features. Signed-off-by:

Since o_seqno is now atomic_t, we can always turn on NETIF_F_LLTX for [IP6]GRE[TAP] devices, since we no longer need the TX lock (&txq->_xmit_lock). We could probably do the same thing to [IP6]ERSPAN devices as well, but I'm not familiar with them yet. For example, ERSPAN devices are initialized as |= GRE_FEATURES in erspan_tunnel_init(), but I don't see IP6ERSPAN devices being initialized as |= GRE6_FEATURES. Where should we initialize IP6ERSPAN devices' ->features? Please suggest if I'm missing something, thanks!
