There is a comments with some chinese semicolons that cause encoding issues each time hns_roc_hw_v2.h was modified from a IDE. So fix this by using correct symbols. Link: https://lore.kernel.org/r/1588242691-12913-2-git-send-email-liweihang@huawei.comSigned-off-by:

Optimize the QP's WQE buffer parameters calculating process to make the codes more readable mainly by merging calculation of extended sge space of kernel and userspace. In addition, add some inline functions to simply codes about multi-hop addressing. Link: https://lore.kernel.org/r/1588071823-40200-4-git-send-email-liweihang@huawei.comSigned-off-by:

The MTT (Memory Translate Table) interface is no longer used to configure the buffer address to BT (Base Address Table) that requires driver mapping. Because the MTT is not compatible with multi-hop addressing of the hip08, it is replaced by MTR (Memory Translate Region) interface, and all the MTT functions should be removed.

PBL table has its own implementation for multi-hop addressing currently, but for the hardware, all table's addressing use the same logic, there is no need to implement repeatedly. So optimize the PBL buffer allocation process by using the mtr's interfaces. Link: https://lore.kernel.org/r/1588071823-40200-2-git-send-email-liweihang@huawei.comSigned-off-by:

When a client is added it isn't allowed to fail, but all the client's have various failure paths within their add routines. This creates the very fringe condition where the client was added, failed during add and didn't set the client_data. The core code will then still call other client_data centric ops like remove(), rename(), get_nl_info(), and get_net_dev_by_params() with NULL client_data - which is confusing and unexpected. If the add() callback fails, then do not call any more client ops for the device, even remove. Remove all the now redundant checks for NULL client_data in ops callbacks. Update all the add() callbacks to return error codes appropriately. EOPNOTSUPP is used for cases where the ULP does not support the ib_device - eg because it only works with IB.

The patch sets the lag tx affinity of the data QPs and the GSI QPs according to the LAG xmit slave. For GSI QPs, in case the link layer is Ethenet (RoCE) we create two GSI QPs, one for each physical port. When the driver selects the GSI QP, it will consider the port affinity result. For connected QPs, the driver sets the affinity of the xmit slave. The above, ensures that RC QP and it's corresponding GSI QP will transmit from the same physical port.

Add support to get the RoCE LAG xmit slave by building skb of the RoCE packet and call to master_get_xmit_slave.

The lag lock could be a spin lock, the critical section is short and there is no need that the thread will sleep. Change the lock that protects the LAG structure from mutex to spin lock. It is required for next patch that need to access this structure from context that we can't sleep. In addition there is no need to hold this lock when query the congestion counters. Signed-off-by:
