Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only. Signed-off-by:

Currently, users can see that bonding supports IPSec HW offload via ethtool. However, this functionality does not work with NICs like Mellanox cards when ESN (Extended Sequence Numbers) is enabled, as ESN functions are not yet supported. This patch adds ESN support to the bonding IPSec device offload, ensuring proper functionality with NICs that support ESN. Reviewed-by:

This patch adds a common function to check the status of IPSec devices. This function will be useful for future implementations, such as IPSec ESN and state offload callbacks. Suggested-by:

This NIC doesn't have hardware IRQ coalescing. Under high load, interrupts can adversely affect performance. To mitigate this, enable software IRQ coalescing by default. On my system this increases receive throughput with iperf3 from 853 MBit/sec to 934 MBit/s, decreases interrupts from 69489/sec to 2016/sec, and decreases CPU utilization from 27% (4x Cortex-A53) to 14%. Latency is not affected (as far as I can tell). Signed-off-by:

When reading registers from the PHY using the SIOCGMIIREG IOCTL any errors returned from either mdiobus_read() or mdiobus_c45_read() are ignored, and parts of the returned error is passed as the register value back to user-space. For example, if mdiobus_c45_read() is used with a bus that do not implement the read_c45() callback -EOPNOTSUPP is returned. This is however directly stored in mii_data->val_out and returned as the registers content. As val_out is a u16 the error code is truncated and returned as a plausible register value. Fix this by first checking the return value for errors before returning it as the register content. Before this patch, # phytool read eth0/0:1/0 0xffa1 After this change, $ phytool read eth0/0:1/0 error: phy_read (-95) Signed-off-by:Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Reviewed-by:

Ido Schimmel says: ==================== Unmask upper DSCP bits - part 3 tl;dr - This patchset continues to unmask the upper DSCP bits in the IPv4 flow key in preparation for allowing IPv4 FIB rules to match on DSCP. No functional changes are expected. The TOS field in the IPv4 flow key ('flowi4_tos') is used during FIB lookup to match against the TOS selector in FIB rules and routes. It is currently impossible for user space to configure FIB rules that match on the DSCP value as the upper DSCP bits are either masked in the various call sites that initialize the IPv4 flow key or along the path to the FIB core. In preparation for adding a DSCP selector to IPv4 and IPv6 FIB rules, we need to make sure the entire DSCP value is present in the IPv4 flow key. This patchset continues to unmask the upper DSCP bits, but this time in the output route path, specifically in the callers of ip_route_output_ports(). The next patchset (last) will handle the callers of ip_route_output_key(). Split from this patchset to avoid going over the 15 patches limit. No functional changes are expected as commit 1fa3314c ("ipv4: Centralize TOS matching") moved the masking of the upper DSCP bits to the core where 'flowi4_tos' is matched against the TOS selector. ==================== Link: https://patch.msgid.link/20240903135327.2810535-1-idosch@nvidia.comSigned-off-by: -

RT_TOS() from include/uapi/linux/in_route.h is defined using IPTOS_TOS_MASK from include/uapi/linux/ip.h. This is problematic for files such as include/net/ip_fib.h that want to use RT_TOS() as without including both header files kernel compilation fails: In file included from ./include/net/ip_fib.h:25, from ./include/net/route.h:27, from ./include/net/lwtunnel.h:9, from net/core/dst.c:24: ./include/net/ip_fib.h: In function ‘fib_dscp_masked_match’: ./include/uapi/linux/in_route.h:31:32: error: ‘IPTOS_TOS_MASK’ undeclared (first use in this function) 31 | #define RT_TOS(tos) ((tos)&IPTOS_TOS_MASK) | ^~~~~~~~~~~~~~ ./include/net/ip_fib.h:440:45: note: in expansion of macro ‘RT_TOS’ 440 | return dscp == inet_dsfield_to_dscp(RT_TOS(fl4->flowi4_tos)); Therefore, cited commit changed linux/in_route.h to include linux/ip.h. However, as reported by David, this breaks iproute2 compilation due overlapping definitions between linux/ip.h and /usr/include/netinet/ip.h: In file included from ../include/uapi/linux/in_route.h:5, from iproute.c:19: ../include/uapi/linux/ip.h:25:9: warning: "IPTOS_TOS" redefined 25 | #define IPTOS_TOS(tos) ((tos)&IPTOS_TOS_MASK) | ^~~~~~~~~ In file included from iproute.c:17: /usr/include/netinet/ip.h:222:9: note: this is the location of the previous definition 222 | #define IPTOS_TOS(tos) ((tos) & IPTOS_TOS_MASK) Fix by changing include/net/ip_fib.h to include linux/ip.h. Note that usage of RT_TOS() should not spread further in the kernel due to recent work in this area. Fixes: 1fa3314c ("ipv4: Centralize TOS matching") Reported-by: -

Commit aa92c1ce ("l2tp: add tunnel/session get_next helpers") uses idr_get_next APIs to iterate over l2tp session IDR lists. Sessions in l2tp_v2_session_idr always have a non-null session->tunnel pointer since l2tp_session_register sets it before inserting the session into the IDR. Therefore the null check on session->tunnel in l2tp_v2_session_get_next is redundant and can be removed. Removing the check avoids a warning from lkp. Reported-by:

Add support for group stats for mac. The fbnic_set_counter help preserve the default values for counters which are not touched by the driver. The 'reset' flag in 'get_eth_mac_stats' allows to choose between resetting the counter to recent most value or fetching the aggregated values of the counter. The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion using read-read-read approach. This allows to isolate cases where counter is moving too fast making accuracy of the counter questionable.

Daniel Machon says: ==================== net: microchip: add FDMA library and use it for Sparx5 This patch series is the first of a 2-part series, that adds a new common FDMA library for Microchip switch chips Sparx5 and lan966x. These chips share the same FDMA engine, and as such will benefit from a common library with a common implementation. This also has the benefit of removing a lot open-coded bookkeeping and duplicate code for the two drivers. Additionally, upstreaming efforts for a third chip, lan969x, will begin in the near future. This chip will use the new library too. In this first series, the FDMA library is introduced and used by the Sparx5 switch driver. ################### # Example of use: # ################### - Initialize the rx and tx fdma structs with values for: number of DCB's, number of DB's, channel ID, DB size (data buffer size), and total size of the requested memory. Also provide two callbacks: nextptr_cb() and dataptr_cb() for getting the nextptr and dataptr. - Allocate memory using fdma_alloc_phys() or fdma_alloc_coherent(). - Initialize the DCB's with fdma_dcb_init(). - Add new DCB's with fdma_dcb_add(). - Free memory with fdma_free_phys() or fdma_free_coherent(). ##################### # Patch breakdown: # ##################### Patch #1: introduces library and selects it for Sparx5. Patch #2: includes the fdma_api.h header and removes old symbols. Patch #3: replaces old rx and tx variables with equivalent ones from the fdma struct. Only the variables that can be changed without breaking traffic is changed in this patch. Patch #4: uses the library for allocation of rx buffers. This requires quite a bit of refactoring in this single patch. Patch #5: uses the library for adding DCB's in the rx path. Patch #6: uses the library for freeing rx buffers. Patch #7: uses the library helpers in the rx path. Patch #8: uses the library for allocation of tx buffers. This requires quite a bit of refactoring in this single patch. Patch #9: uses the library for adding DCB's in the tx path. Patch #10: uses the library helpers in the tx path. Patch #11: ditches the existing linked list for storing buffer addresses, and instead uses offsets into contiguous memory. Patch #12: modifies existing rx and tx functions to be direction independent. ==================== Signed-off-by: -

These direction specific functions can be ditched in favor of a single function: sparx5_fdma_reload(), which retrieves the channel id from the fdma struct instead. Signed-off-by:

Currently, the driver uses a linked list for storing the tx buffer addresses. This requires a good amount of extra bookkeeping code. Ditch the linked list in favor of tx buffers being in the same contiguous memory space as the DCB's and the DB's. The FDMA library has a helper for this - so use that. The tx buffer addresses are now retrieved as an offset into the FDMA memory space. Signed-off-by:
