Currently, the debugfs command for ncl config is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "ncl_config" for it, and query it by command "cat ncl_config", return the result to userspace, rather than record in dmesg. The display style is below: $cat ncl_config offset | data 0x0000 | 0x00000028 0x0004 | 0x00000400 0x0008 | 0x08040201 0x000c | 0x00000000 0x0010 | 0x00040004 0x0014 | 0x00040004 0x0018 | 0x00000000 0x001c | 0x00000000 0x0020 | 0x00040004 Signed-off-by:

Only when RXD advanced layout is enabled, in some cases (e.g. ip fragments), the checksum of entire packet will be calculated and filled in the least significant 16 bits of the unused addr field. So refactor out the handling of RX completion checksum: adjust the location of the checksum in RX descriptor, and use ptype table to identify whether this kind of checksum is calculated.

Currently, the driver gets packet type by parsing the L3_ID/L4_ID/OL3_ID/OL4_ID from RX descriptor, it's time-consuming. Now some new devices support RXD advanced layout, which combines previous OL3_ID/OL4_ID to 8bit ptype field, so the driver gets packet type by looking up only one table, and L3_ID/L4_ID become reserved fields. Considering compatibility, the firmware will report capability of RXD advanced layout, the driver will identify and enable it by default. This patch provides basic function: identify and enable the RXD advanced layout, and refactor out hns3_rx_checksum() by using ptype table to handle RX checksum if supported. Signed-off-by:

The first parameter passed to chnl_recv_cb() can never be NULL since all callers dereferenced it. Consequently, container_of() on it is also never NULL, even though the reference into the structure points to the first element of the structure. The NULL check is therefore unnecessary. On top of that, it is misleading to perform a NULL check on the result of container_of() because the position of the contained element could change, which would make the test invalid. Remove the unnecessary NULL check. This change was made automatically with the following Coccinelle script. @@ type t; identifier v; statement s; @@ <+...

Xuan Zhuo says: ==================== virtio-net: fix for build_skb() The logic of this piece is really messy. Fortunately, my refactored patch can be completed with a small amount of testing. ==================== Signed-off-by: -
Xuan Zhuo authored
In the case of merge, the page passed into page_to_skb() may be a head page, not the page where the current data is located. So when trying to get the buf where the data is located, you should directly use the pointer(p) to get the address corresponding to the page. At the same time, the offset of the data in the page should also be obtained using offset_in_page(). This patch solves this problem. But if you don’t use this patch, the original code can also run, because if the page is not the page of the current data, the calculated tailroom will be less than 0, and will not enter the logic of build_skb() . The significance of this patch is to modify this logical problem, allowing more situations to use build_skb(). Signed-off-by:

In merge mode, when xdp is enabled, if the headroom of buf is smaller than virtnet_get_headroom(), xdp_linearize_page() will be called but the variable of "headroom" is still 0, which leads to wrong logic after entering page_to_skb().

Mikrotik 10/25G NIC supports hw checksum verification on rx for IP/IPv6 + TCP/UDP packets. HW checksum offload helps reduce host cpu load. This enables the csum offload specifically for Mikrotik 10/25G NIC as other HW supported by the driver is known to have problems with it. TCP iperf3 to Threadripper 3960X with NIC improved 16.5 -> 20.0 Gbps with mtu=1500. Signed-off-by:

The kernel has xmit_more facility that hints the networking driver xmit path about whether more packets are coming soon. This information can be used to avoid unnecessary expensive PCIe transaction per tx packet. Max TX pps on Mikrotik 10/25G NIC in a Threadripper 3960X system improved from 1150Kpps to 1700Kpps.

Linus Lüssing says: ==================== net: bridge: split IPv4/v6 mc router state and export for batman-adv The following patches are splitting the so far combined multicast router state in the Linux bridge into two ones, one for IPv4 and one for IPv6, for a more fine-grained detection of multicast routers. This avoids sending IPv4 multicast packets to an IPv6-only multicast router and avoids sending IPv6 multicast packets to an IPv4-only multicast router. This also allows batman-adv to make use of the now split information in the final patch. The first eight patches prepare the bridge code to avoid duplicate code or IPv6-#ifdef clutter for the multicast router state split. And contain no functional changes yet. The ninth patch then implements the IPv4+IPv6 multicast router state split. Patch number ten adds IPv4+IPv6 specific timers to the mdb netlink router port dump, so that the timers validity can be checked individually from userspace. The final, eleventh patch exports this now per protocol family multicast router state so that batman-adv can then later make full use of the Multicast Router Discovery (MRD) support in the Linux bridge. The batman-adv protocol format currently expects separate multicast router states for IPv4 and IPv6, therefore it depends on the first patch. batman-adv will then make use of this newly exported functions like this[0].
