After extended testing, it was found that the previous PCIe Gen 3 recipe, which used adaptive CTLE with Preset 4, could cause an NMI/Surprise Link Down in about 1 in 100 to 1 in 1000 power cycles on some platforms. New EV data combined with extensive empirical data indicates that the new recipe should use static CTLE with Preset 6 for all integrated silicon SKUs.

In the event that the IRQ thread is extremely busy, the processing of an rcd wait list can be delayed by quite a bit until the IRQ thread completes its work. The QP reset reference count wait can then appear to be stuck, thus causing up a QP destroy to emit the hung task diagnostic. Fix by processing the qp wait list periodically from the thread. The interval is a multiple (currently 4) of the MAX_PKT_RECV. Also, reduce some of the excessive inlining. The guidelines are per packet is ok inline, otherwise the choice is based on likelyhood of execution. Reviewed-by:

The destination address in a listening rdma_id does not have an address family. Since address family in both sides of a connection must be the same in rdma_bind_addr() we set the address family of the destination to the address family of the source. This patch serves the logic in cma_port_is_unique() which requires to know if destination address that is associated with a rdma_id is any address (cma_zero_addr() and cma_loopback_addr()). This can happen when port reuse is checked for a port number that is being listened to. Fixes: 19b752a1 ("IB/cma: Allow port reuse for rdma_id") Signed-off-by:

Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.

When sending packet to destination that was not resolved yet via path query, the driver keeps the skb and tries to re-send it again when the path is resolved. But when re-sending via dev_queue_xmit the kernel doesn't call to dev_hard_header, so IPoIB needs to keep 20 bytes in the skb and to put the destination address inside them. In that way the dev_start_xmit will have the correct destination, and the driver won't take the destination from the skb->data, while nothing exists there, which causes to packet be be dropped. The test flow is: 1. Run the SM on remote node, 2. Restart the driver. 4. Ping some destination, 3. Observe that first ICMP request will be dropped.

This patch introduces the RoCE driver for the Broadcom NetXtreme-E 10/25/40/50G RoCE HCAs. The RoCE driver is a two part driver that relies on the parent bnxt_en NIC driver to operate. The changes needed in the bnxt_en driver have already been incorporated via Dave Miller's net tree into the mainline kernel. The vendor official git repository for this driver is available on github as: https://github.com/Broadcom/linux-rdma-nxt/Signed-off-by:

Make it possible to configure this information before a subnet prefix has been assigned to a port by not only accepting GIDs as target port and initiator port names but by also accepting port GUIDs.

If IPV6 has not been enabled in the underlying kernel, we must avoid calling IPV6 procedures in rdma_cm.ko. This requires using "IS_ENABLED(CONFIG_IPV6)" in "if" statements surrounding any code which calls external IPV6 procedures. In the instance fixed here, procedure cma_bind_addr() called ipv6_addr_type() -- which resulted in calling external procedure __ipv6_addr_type().

When allocating a port number for binding to a rdma_id, assuming the allocation is not for a specific port, the rule is to allow only ports that were not in use before by any other rdma_id. This condition is too strong to achieve the goal of a unique 5 tuple rdma_id. Instead, we can compare current rdma_id with other rdma_id for difference in one of destination port, source address and destination address to allow port reuse. Signed-off-by:
