net: Fix features skip in for_each_netdev_feature()

2022-05-06T01:25:57+00:00

The find_next_netdev_feature() macro gets the "remaining length", not bit index. Passing "bit - 1" for the following iteration is wrong as it skips the adjacent bit. Pass "bit" instead.

net: hsr: add offloading support

2021-02-11T21:24:44+00:00

Add support for offloading of HSR/PRP (IEC 62439-3) tag insertion tag removal, duplicate generation and forwarding. For HSR, insertion involves the switch adding a 6 byte HSR header after the 14 byte Ethernet header. For PRP it adds a 6 byte trailer. Tag removal involves automatically stripping the HSR/PRP header/trailer in the switch. This is possible when the switch also performs auto deduplication using the HSR/PRP header/trailer (making it no longer required). Forwarding involves automatically forwarding between redundant ports in an HSR. This is crucial because delay is accumulated as a frame passes through each node in the ring. Duplication involves the switch automatically sending a single frame from the CPU port to both redundant ports. This is required because the inserted HSR/PRP header/trailer must contain the same sequence number on the frames sent out both redundant ports. Export is_hsr_master so DSA can tell them apart from other devices in dsa_slave_changeupper. Signed-off-by: George McCollister Reviewed-by: Vladimir Oltean Signed-off-by: David S. Miller

net: introduce a netdev feature for UDP GRO forwarding

2021-01-24T04:16:24+00:00

Introduce a new netdev feature, NETIF_F_GRO_UDP_FWD, to allow user to turn UDP GRO on and off for forwarding. Defaults to off to not change current datapath. Suggested-by: Paolo Abeni Signed-off-by: Alexander Lobakin Signed-off-by: Jakub Kicinski

net: add GSO UDP L4 and GSO fraglists to the list of software-backed types

2020-11-04T00:53:55+00:00

Commit e20cf8d3f1f7 ("udp: implement GRO for plain UDP sockets.") and commit 9fd1ff5d2ac7 ("udp: Support UDP fraglist GRO/GSO.") made UDP L4 and fraglisted GRO/GSO fully supported by the software fallback mode. We can safely add them to NETIF_F_GSO_SOFTWARE to allow logical/virtual netdevs to forward these types of skbs up to the real drivers.
