Those files under /proc/net/stat/ don't have vertical alignment, it looks very difficult. Modify the seq_printf statement, keep vertical alignment. v2: - Use seq_puts() and seq_printf() correctly. Reported-by:

Add an option lacp_active, which is similar with team's runner.active. This option specifies whether to send LACPDU frames periodically. If set on, the LACPDU frames are sent along with the configured lacp_rate setting. If set off, the LACPDU frames acts as "speak when spoken to". Note, the LACPDU state frames still will be sent when init or unbind port. v2: remove module parameter Signed-off-by:

strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. The safe replacement is strscpy(). Signed-off-by:

Vasily Averin says: ==================== skbuff: introduce skb_expand_head() currently if skb does not have enough headroom skb_realloc_headrom is called. It is not optimal because it creates new skb. this patch set introduces new helper skb_expand_head() Unlike skb_realloc_headroom, it does not allocate a new skb if possible; copies skb->sk on new skb when as needed and frees original skb in case of failures. This helps to simplify ip[6]_finish_output2(), ip6_xmit() and few other functions in vrf, ax25 and bpf. There are few other cases where this helper can be used but it requires an additional investigations. v3 changes: - ax25 compilation warning fixed - v5.14-rc4 rebase - now it does not depend on non-committed pathces v2 changes: - helper's name was changed to skb_expand_head - fixed few mistakes inside skb_expand_head(): skb_set_owner_w should set sk on nskb kfree was replaced by kfree_skb() improved warning message - added minor refactoring in changed functions in vrf and bpf patches - removed kfree_skb() in ax25_rt_build_path caller ax25_ip_xmit ==================== Signed-off-by: -

Like skb_realloc_headroom(), new helper increases headroom of specified skb.

Saeed Mahameed says: ==================== This patch-set changes the TTC (Traffic Type Classification) logic to be independent from the mlx5 ethernet driver by renaming the traffic types enums and making the TTC API generic to the mlx5 core driver. It allows to decouple TTC logic from mlx5e and reused by other parts of mlx5 drivers, namely ADQ and lag TX steering hashing. Patches overview: 1 - Rename traffic type enums to be mlx5 generic. 2 - Rename related TTC arguments and functions. 3 - Remove dependency in the mlx5e driver from the TTC implementation. 4 - Move TTC logic to fs_ttc. 5 - Embed struct mlx5_ttc_table in fs_ttc. The refactoring series is followed by misc' cleanup patches. ==================== Signed-off-by: -

Passing parse_attr is redundant in parse_tc_nic_actions() and mlx5e_tc_add_nic_flow() as we can get it from flow. This is the same as with parse_tc_fdb_actions() and mlx5e_tc_add_fdb_flow(). Signed-off-by:

The channels array in struct mlx5e_rx_res is converted to a dynamic one, which will use the dynamic value of max_nch instead of implementation-defined maximum of MLX5E_MAX_NUM_CHANNELS. Signed-off-by:

Maxim Mikityanskiy authored
This commit moves all implementation details of struct mlx5e_rx_res under en/rx_res.c. All access to RX resources is now done using methods. Encapsulating RX resources into an object allows for better manageability, because all the implementation details are now in a single place, and external code can use only a limited set of API methods to init/teardown the whole thing, reconfigure RSS and LRO parameters, connect TIRs to flow steering and activate/deactivate TIRs. mlx5e_rx_res is self-contained and doesn't depend on struct mlx5e_priv or include en.h.

Currently, struct mlx5e_channels is defined in en.h, along with a lot of other stuff. In the following commit mlx5e_rx_res will need to get RQNs (RQ hardware IDs), given a pointer to mlx5e_channels and the channel index. In order to make it possible without including the whole en.h, this commit introduces functions that will hide the implementation details of mlx5e_channels. Signed-off-by:

Replace mlx5e_build_default_indir_rqt with a new initializer of struct mlx5e_rss_params_indir that works directly with the struct, rather than its internals. The new initializer is called mlx5e_rss_params_indir_init_uniform, which also reflects the purpose (uniform spreading) better. Signed-off-by:
