On GOP port 0 two MAC modes are available: GMAC and XLG. The XLG MAC is used for 10G connectivity. This patch adds a basic 10G support by allowing to use the XLG MAC on port 0 and by reworking the port_enable/disable functions so that the XLG MAC is configured when using 10G.

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: port macros cosmetics This patch series brings no functional changes. It prefixes all common port registers macros with MV88E6XXX_PORT. If registers or some bits differs between switch models, a reference model is chosen (e.g. MV88E6390_PORT_MAC_CTL_SPEED_10000.) The register names are documented as found in the datasheets. Avoid BIT() and shifts defines and prefer a better representation of the Marvell switch registers with ordered, hexadecimal, 16-bit values. ==================== Signed-off-by: NDavid S.

Paolo Abeni says: ==================== udp: reduce cache pressure In the most common use case, many skb fields are not used by recvmsg(), and the few ones actually accessed lays on cold cachelines, which leads to several cache miss per packet. This patch series attempts to reduce such misses with different strategies: * caching the interesting fields in the scratched space * avoid accessing at all uninteresting fields * prefetching Tested using the udp_sink program by Jesper[1] as the receiver, an h/w l4 rx hash on the ingress nic, so that the number of ingress nic rx queues hit by the udp traffic could be controlled via ethtool -L. The udp_sink program was bound to the first idle cpu, to get more stable numbers.

when udp_recvmsg() is executed, on x86_64 and other archs, most skb fields are on cold cachelines. If the skb are linear and the kernel don't need to compute the udp csum, only a handful of skb fields are required by udp_recvmsg(). Since we already use skb->dev_scratch to cache hot data, and there are 32 bits unused on 64 bit archs, use such field to cache as much data as we can, and try to prefetch on dequeue the relevant fields that are left out. This can save up to 2 cache miss per packet. v1 -> v2: - changed udp_dev_scratch fields types to u{32,16} variant, replaced bitfiled with bool Signed-off-by: NPaolo Abeni <pabeni@redhat.com> Acked-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.

Since UDP no more uses sk->destructor, we can clear completely the skb head state before enqueuing. Amend and use skb_release_head_state() for that. All head states share a single cacheline, which is not normally used/accesses on dequeue. We can avoid entirely accessing such cacheline implementing and using in the UDP code a specialized skb free helper which ignores the skb head state. This saves a cacheline miss at skb deallocation time. v1 -> v2: replaced secpath_reset() with skb_release_head_state() Signed-off-by: NPaolo Abeni <pabeni@redhat.com> Acked-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.

Saeed Mahameed says: ==================== mlx5-updates-2017-06-11 This series provides updates to mlx5 header rewrite feature, from Or Gerlitz. and three more small updates From maor and eran. ------- Or says: Packets belonging to flows which are different by matching may still need to go through the same header re-writes (e.g set the current routing hop MACs and issue TTL decrement). To minimize the number of modify header IDs, we add a cache for header re-write IDs which is keyed by the binary chain of modify header actions. The caching is supported for both eswitch and NIC use-cases, where the actual conversion of the code to use caching comes in separate patches, one per use-case. Using a per field mask field, the TC pedit action supports modifying partial fields. The last patch enables offloading that. ------- From Maor, update flow table commands layout to the latest HW spec. From Eran, ethtool connector type reporting updates. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
