Provide infrastructure for PHY drivers to report the cable test results. A netlink skb is associated to the phydev. Helpers will be added which can add results to this skb. Once the test has finished the results are sent to user space. When netlink ethtool is not part of the kernel configuration stubs are provided.

2020-05-10net: phy: Add cable test support to state machineAndrew Lunn
Running a cable test is desruptive to normal operation of the PHY and can take a 5 to 10 seconds to complete. The RTNL lock cannot be held for this amount of time, and add a new state to the state machine for running a cable test. The driver is expected to implement two functions. The first is used to start a cable test. Once the test has started, it should return. The second function is called once per second, or on interrupt to check if the cable test is complete, and to allow the PHY to report the status. v2: Rename phy_cable_test_abort to phy_abort_cable_test Return different extack when already running test Use phy_init_hw() to reset the PHY Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-05-09octeontx2-pf: Use the napi_alloc_frag() to alloc the pool buffersKevin Hao
In the current codes, the octeontx2 uses its own method to allocate the pool buffers, but there are some issues in this implementation. 1. We have to run the otx2_get_page() for each allocation cycle and this is pretty error prone. As I can see there is no invocation of the otx2_get_page() in otx2_pool_refill_task(), this will leave the allocated pages have the wrong refcount and may be freed wrongly. 2. It wastes memory. For example, if we only receive one packet in a NAPI RX cycle, and then allocate a 2K buffer with otx2_alloc_rbuf() to refill the pool buffers and leave the remain area of the allocated page wasted. On a kernel with 64K page, 62K area is wasted. IMHO it is really unnecessary to implement our own method for the buffers allocate, we can reuse the napi_alloc_frag() to simplify our code.

2020-05-09net: atlantic: unify MAC generationMark Starovoytov
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.

2020-05-09net/mlx5e: Split TX acceleration offloads into two phasesMaxim Mikityanskiy
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).

2020-05-09net/mlx5e: Make TLS offload independent of wqe and piMaxim Mikityanskiy
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.

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: Saeed Mahameed <saeedm@mellanox.com>
