The current code enables up to the maximum MSIX vectors in the PCIE config space without considering the max completion rings available. An MSIX vector is only useful when it has an associated completion ring, so it is better to cap it. Signed-off-by:

No offload is performed on the XDP_TX ring so we can use the short TX BDs. This has the effect of doubling the size of the XDP TX ring so that it now matches the size of the rx ring by default. Signed-off-by:

The mac loopback self test operates in polling mode. To support that, we need to add functions to open and close the NIC half way. The half open mode allows the rings to operate without IRQ and NAPI. We use the XDP transmit function to send the loopback packet. Signed-off-by:

Yuval Mintz says: ==================== qed: QM & ILT changes This series introduces several changes and improvements to existing queue manager and ILT configurations done during initialization. Notice some of the patches are actually future fixes, I.e., bugs that can't be triggered with exisiting driver but are needed for some future functionality. Patch #1 refactors the configuration of the hardware's queue manager, which is quite messy today. This contains most of the bulk [code-wise] in the series. Patch #2, #3 fix Timers related ILT configurations that are yet to affect qed in existing scenarios. Patch #4 reduces needless ILT lines wasted for RoCE configurations. Patch #5 allows RoCE partitions to manage with less memory regions [important, e.g., for Multi-function parititions with RoCE support]. ==================== Signed-off-by: -

It's possible some configurations would prevent driver from utilizing all the Memory Regions due to a lack of ILT lines. In such a case, calculate how many memory regions would have to be dropped due to limit, and manage without those. Signed-off-by:

As RoCE doesn't need to use the SRC, allocating ILT memory on behalf of RoCE is wasting available ILT lines. Signed-off-by:

As of today there's no protocol supported that requires support from the TM hardware block and enables SRIOV, but we should still correct the calculation to reflect the lines required for such future VFs instead of changing the PF's own lines. Signed-off-by:

When configuring the HW timers block we should set the number of CIDs up until the last CID that require timers, instead of only those CIDs whose protocol needs timers support. Today, the protocols that require HW timers' support have their CIDs before any other protocol, but that would change in future [when we add iWARP support]. Signed-off-by:

Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms. Signed-off-by:

Number of sockets is limited by 16-bit, so 64-bit allocation will never happen. 16-bit ops are the worst code density-wise on x86_64 because of additional prefix (66).

Make ->hash_count, ->low_watermark and ->high_watermark unsigned int and propagate unsignedness to other variables. This change doesn't change code generation because these fields aren't used in 64-bit contexts but make it anyway: these fields can't be negative numbers. Signed-off-by:

When an incoming frame is tagged or when GRO is disabled, the skb handled to vxlan_xmit() doesn't contain a valid transport header offset. This makes ND proxying fail. We combine two changes: replace use of skb_transport_offset() and ensure the necessary amount of skb is linear just before using it: - In vxlan_xmit(), when determining if we have an ICMPv6 neighbor discovery packet, just check if it is an ICMPv6 packet and rely on neigh_reduce() to do more checks if this is the case. The use of pskb_may_pull() is replaced by skb_header_pointer() for just the IPv6 header. - In neigh_reduce(), add pskb_may_pull() for IPv6 header and neighbor discovery message since this was removed from vxlan_xmit(). Replace skb_transport_header() with ipv6_hdr() + 1. - In vxlan_na_create(), replace first skb_transport_offset() with ipv6_hdr() + 1 and second with skb_network_offset() + sizeof(struct ipv6hdr). Additionally, ensure we pskb_may_pull() the whole skb as we need it to iterate over the options. Signed-off-by:

Before when implementing sctp prsctp, SCTP_PR_STREAM_STATUS wasn't added, as it needs to save abandoned_(un)sent for every stream. After sctp stream reconf is added in sctp, assoc has structure sctp_stream_out to save per stream info. This patch is to add SCTP_PR_STREAM_STATUS by putting the prsctp per stream statistics into sctp_stream_out. v1->v2: fix an indent issue. Signed-off-by:

There is a bug on Hip06 that tx ring interrupts packets count will be clear when drivers send data to tx ring, so that the tx packets count will never upgrade to packets line, and cause the interrupts engendered was delayed. Sometimes, it will cause sending performance lower than expected. To fix this bug, we set tx ring interrupts packets line to 1 forever, to avoid count clear. And set the gap time to 20us, to solve the problem that too many interrupts engendered when packets line is 1. This patch could advance the send performance on ARM from 6.6G to 9.37G when an iperf send thread on ARM and an iperf send thread on X86 for XGE. Signed-off-by:

Because buf_size of ring set to 2048, the process of rx_poll_one can reuse the page, therefore the performance of XGE can improve. But the chip only supports three bds in one package, so the max mtu is 6K when it sets to 2048. For better performane in litter mtu, we need change buf_size according to mtu. When user change mtu, hns is only change the desc in memory. There are some desc has been fetched by the chip, these desc can not be changed by the code. So it needs set the port loopback and send some packages to let the chip consumes the wrong desc and fetch new desc. Because the Pv660 do not support rss indirection, we need add version check in mtu change process. Signed-off-by:
