On ingress, the matchall rules doing mirroring and sampling are offloaded into hardware blocks that are processed before any flower rules. On egress, the matchall mirroring rules are offloaded into hardware block that is processed after all flower rules. Therefore check the priorities of inserted matchall rules against existing flower rules and ensure the correct ordering. Signed-off-by:

Introduce an infrastructure that allows to get minimum and maximum rule priority for specified chain. This is going to be used by a subsequent patch to enforce ordering between flower and matchall filters. Signed-off-by:

This patch unifies invalid MAC address handling with other drivers. Basically we've switched to using standard APIs (is_valid_ether_addr / eth_hw_addr_random) where possible. It's worth noting that some of engineering Aquantia NICs might be provisioned with a partially zeroed out MAC, which is still invalid, but not caught by is_valid_ether_addr(), so we've added a special handling for this case. Also adding a warning in case of fallback to random MAC, because this shouldn't be needed on production NICs, they should all be provisioned with unique MAC. NB! Default systemd/udevd configuration is 'MACAddressPolicy=persistent'. This causes MAC address to be persisted across driver reloads and reboots. We had to change it to 'none' for verification purposes. Signed-off-by:Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by:

The same WQE opcode might be used in different ICOSQ flows and WQE types. To have a better distinguishability, replace it with an enum that better indicates the WQE type and flow it is used for. Signed-off-by:

Every single DUMP WQE resides in a single WQEBB. As the pi is calculated per each one separately, there is no real need for a contiguous room for them, allow them to populate different WQ fragments. This reduces WQ waste and improves its utilization. Signed-off-by:

After previous modifications, the offloads are no longer called one by one, the pi is calculated and the wqe is cleared on between of TLS and IPSEC offloads, which doesn't quite fit mlx5e_accel_handle_tx's purpose. This patch splits mlx5e_accel_handle_tx into two functions that correspond to two logical phases of running offloads: 1. Before fetching a WQE. Here runs the code that can post WQEs on its own, before the main WQE is fetched. It's the main part of TLS offload. 2. After fetching a WQE. Here runs the code that updates the WQE's fields, but can't post other WQEs any more. It's a minor part of TLS offload that sets the tisn field in the cseg, and eseg-based offloads (currently IPSEC, and later patches will move GENEVE and checksum offloads there, too). It allows to make mlx5e_xmit take care of all actions needed to transmit a packet in the right order, improve the structure of the code and reduce unnecessary operations. The structure will be further improved in the following patches (all eseg-based offloads will be moved to a single place, and reserving space for the main WQE will happen between phase 1 and phase 2 of offloads to eliminate unneeded data movements).

mlx5e_udp_gso_handle_tx_skb updates the length field in the UDP header in case of GSO. It doesn't interfere with other offloads, so do it first to simplify further restructuring of the code. This way we'll make all independent modifications to the SKB before starting to work with WQEs. Signed-off-by:

TLS offload may write a 32-bit field (tisn) to the cseg of the WQE. To do that, it receives pi and wqe pointers. As TLS offload may also send additional WQEs, it has to update pi and wqe, and in many cases it even doesn't use pi calculated before and wqe zeroed before and does it itself. Also, mlx5e_sq_xmit has to copy the whole cseg if it goes to the mlx5e_fill_sq_frag_edge flow. This all is not efficient. It's more efficient to do the following: 1. Just return tisn from TLS offload and make the caller fill it in a more appropriate place. 2. Calculate pi and clear wqe after calling TLS offload. 3. If TLS offload has to send WQEs, calculate pi and clear wqe just before that. It's already done in all places anyway, so this commit allows to remove some redundant memsets and calls. Copying of cseg will be eliminated in one of the following commits, and all other stuff is done here. Signed-off-by:

IPSEC offload needs to modify the eseg of the WQE that is being filled, but it receives a pointer to the whole WQE. To make the contract stricter, pass only the pointer to the eseg of that WQE. This commit is preparation for the following refactoring of offloads in the TX path and for the MPWQE support. Signed-off-by:

TLS and IPSEC offloads currently return struct sk_buff *, but the value is either NULL or the same skb that was passed as a parameter. Return bool instead to provide stronger guarantees to the calling code (it won't need to support handling a different SKB that could be potentially returned before this change) and to simplify restructuring this code in the following commits.

This merge includes updates to bonding driver needed for the rdma stack, to avoid conflicts with the RDMA branch. Maor Gottlieb Says: ==================== Bonding: Add support to get xmit slave The following series adds support to get the LAG master xmit slave by introducing new .ndo - ndo_get_xmit_slave. Every LAG module can implement it and it first implemented in the bond driver. This is follow-up to the RFC discussion [1]. The main motivation for doing this is for drivers that offload part of the LAG functionality. For example, Mellanox Connect-X hardware implements RoCE LAG which selects the TX affinity when the resources are created and port is remapped when it goes down. The first part of this patchset introduces the new .ndo and add the support to the bonding module. The second part adds support to get the RoCE LAG xmit slave by building skb of the RoCE packet based on the AH attributes and call to the new .ndo. The third part change the mlx5 driver driver to set the QP's affinity port according to the slave which found by the .ndo. ==================== Signed-off-by: -

We currently have to adjust ipv6 route gc_thresh/max_size depending on number of cpus on a server, this makes very little sense. If the kernels sets /proc/sys/net/ipv6/route/gc_thresh to 1024 and /proc/sys/net/ipv6/route/max_size to 4096, then we better not track the percpu dst that our implementation uses. Only routes not added (directly or indirectly) by the admin should be tracked and limited. Signed-off-by:
