The existing DSA binding has a number of limitations and problems. The main problem is that it cannot represent a switch as a linux device, hanging off some bus. It is limited to one CPU port. The DSA platform device is artificial, and does not really represent hardware. Implement a new binding which can be embedded into any type of node on a bus to represent one switch device, and its links to other switches.

Have the switch driver register its own MDIO bus.

The switch implements a generic MDIO bus, which could host more than PHYs. It is conventional to use _mdio_ or _mii_ in the function name, so rename them. Also postfix make the historically first read/write function with _direct, to help distinguish it from _indirect and _ppu. While touching these functions, remove some of the _ prefixes, which we are deprecating.

Move the port device node structure into the port structure, from the chip data. This information is needed in the next step of implementing the new binding. The chip data structure is used while parsing the whole old binding, before the individual switch structures exist. With the new bindings, this is reversed, the switches exist first, and the interconnections between the switches is derived from the individual switch bindings. Thus this chip data structure becomes unneeded.

SCTP has this pecualiarity that its packets cannot be just segmented to (P)MTU. Its chunks must be contained in IP segments, padding respected. So we can't just generate a big skb, set gso_size to the fragmentation point and deliver it to IP layer. This patch takes a different approach. SCTP will now build a skb as it would be if it was received using GRO. That is, there will be a cover skb with protocol headers and children ones containing the actual segments, already segmented to a way that respects SCTP RFCs. With that, we can tell skb_segment() to just split based on frag_list, trusting its sizes are already in accordance. This way SCTP can benefit from GSO and instead of passing several packets through the stack, it can pass a single large packet. v2: - Added support for receiving GSO frames, as requested by Dave Miller. - Clear skb->cb if packet is GSO (otherwise it's not used by SCTP) - Added heuristics similar to what we have in TCP for not generating single GSO packets that fills cwnd. v3: - consider sctphdr size in skb_gso_transport_seglen() - rebased due to 5c7cdf33 ("gso: Remove arbitrary checks for unsupported GSO") Signed-off-by: NMarcelo Ricardo Leitner <marcelo.leitner@gmail.com> Tested-by: NXin Long <lucien.xin@gmail.com> Signed-off-by: NDavid S.

This patch is a preparation for the GSO one. In order to successfully handle GSO packets on rx path we must not call skb_linearize, otherwise it defeats any gain GSO may have had. This patch thus delays as much as possible the call to skb_linearize, leaving it to sctp_inq_pop() moment. For that the sanity checks performed now know how to deal with fragments. One positive side-effect of this is that if the socket is backlogged it will have the chance of doing it on backlog processing instead of during softirq. With this move, it's evident that a check for non-linearity in sctp_inq_pop was ineffective and is now removed. Note that a similar check is performed a bit below this one.

skb_gso_network_seglen is not enough for checking fragment sizes if skb is using GSO_BY_FRAGS as we have to check frag per frag. This patch introduces skb_gso_validate_mtu, based on the former, which will wrap the use case inside it as all calls to skb_gso_network_seglen were to validate if it fits on a given TMU, and improve the check.

NETIF_F_GSO_SOFTWARE was defined to list all GSO software types, so lets make use of it in loopback code. Note that veth/vxlan/others already uses it. Within this patch series, this patch causes lo to pick up SCTP GSO feature automatically (as it's added to NETIF_F_GSO_SOFTWARE) and thus avoiding segmentation if possible.

alloc_workqueue replaces deprecated create_workqueue(). The workqueue adapter->txrx_wq has workitem &adapter->raise_intr_rxdata_task per adapter. Extended Socket Network Device is shared memory based, so someone's transmission denotes other's reception. raise_intr_rxdata_task raises interruption of receivers from the sender in order to notify receivers. The workqueue adapter->control_wq has workitem &adapter->interrupt_watch_task per adapter. interrupt_watch_task is used to prevent delay of interrupts. Dedicated workqueues have been used in both cases since the workitems on the workqueues are involved in normal device operation and require forward progress under memory pressure. max_active has been set to 0 since there is no need for throttling the number of active work items. Since network devices may be used for memory reclaim, WQ_MEM_RECLAIM has been set to guarantee forward progress.

The New QED firmware contains several fixes, including: - Wrong classification of packets in 4-port devices. - Anti-spoof interoperability with encapsulated packets. - Tx-switching of encapsulated packets. It also slightly improves Tx performance of the device. In addition, this firmware contains the necessary logic for supporting iscsi & rdma, for which we plan on pushing protocol drivers in the imminent future.

The VRF device exists to define L3 domains and guide FIB lookups. As such its operstate is not relevant. Seeing 'state UNKNOWN' in the output of 'ip link show' can be confusing, so set operstate at link create. Similarly, the MTU for a VRF device is not used; any fragmentation of the payload is done on the output path based on the real egress device. An MTU of 1500 on the VRF device while enslaved devices have a higher MTU can lead to confusion. Since the VRF MTU is not relevant set to 64k similar to what is done for loopback.
