In pin_vector_pages() function, if there is any error while pinning the pages or while adding a pinned buffer to the cache, the bail out code needs to unpin any pinned pages that are not in the cache and adjust the n_locked counter that counts the total pages pinned. The current bail out code doesn't seem to be doing it right in two cases: 1. Before pinning required pages for a buffer, the SDMA pinned buffer cache is searched to see if the virtual address range that needs to be pinned is already pinned. If there isn't a hit in the cache, a new node is created for the buffer and is added to the cache after the buffer is pinned. If adding the new node to the cache fails, the n_locked count is decremented properly but the pinned pages are not freed. This commit fixes this issue. 2. If there is a hit in the SDMA cache, but the cached buffer doesn't have enough pages to cover the entire address range that needs to be pinned, the node for the cached buffer is extracted from the cache, remaining pages needed are pinned and added to the node. The node is finally added back into the cache. If there is an error pinning the extra pages, the bail out code frees all the pages in the node but the n_locked count is not being decremented by the no of pages in the node that are freed. This commit fixes this issue. This commit fixes the above two issues by creating a new function that frees the pages in a node and decrements the n_locked count by the number of pages freed.

Section 9.7.7.2.5 of the 1.3 IBTA spec clearly says that receive credits should never apply to RDMA write. qib and hfi1 were doing that. The following situation will result in a QP hang: - A prior SEND or RDMA_WRITE with immmediate consumed the last credit for a QP using RC receive buffer credits - The prior op is acked so there are no more acks - The peer ULP fails to post receive for some reason - An RDMA write sees that the credits are exhausted and waits - The peer ULP posts receive buffers - The ULP posts a send or RDMA write that will be hung The fix is to avoid the credit test for the RDMA write operation.

Set underlay QPN as part of flow rule when it's applicable. There is one root flow table in the NIC RX namespace and all the underlay QPs steer the traffic to this flow table. In order to prevent QP to get traffic which is not target to its underlay QP, we need to set the underlay QP number as part of the steering matching. Note: When multicast traffic is sent the QPN filtering is done by the firmware as some early step. Adding the QPN match on the flow table entry is wrong as by that time the target QPN holds the multicast address (e.g. FF(s)) and it won't match.

mlx5 compatible devices have two ways of populating the MTT table of an MKEY: using a FW command and using a UMR WQE. A UMR is much faster, so it should be used whenever possible. Unfortunately the code today uses UMR only if the MKEY was allocated from the MR cache. Fix the code to use UMR even for MKEYs that were allocated using a FW command.

Software parsing (SWP) is a feature that can be used to instruct the device to stop using its internal parser and to parse packets on the transmit path according to offsets set for each packets. Through this feature, the device allows the handling of checksum and LSO by the hardware according to the location of IP and TCP/UDP headers. Enable SW parsing on Raw Ethernet send queue by default if firmware supports it and report these capabilities to user space.

IB CM calls ib_modify_port() irrespective of link layer. If the failure is returned, the mad agent gets unregistered for those devices. Recently, modify_port() hook was removed from some of the low level drivers as it was always returning success. This breaks rdma connection establishment over those devices. For ethernet devices, Qkey violation and port capabilities are not applicable. So returning success for RoCE when modify_port hook is is not implemented.
