If anyone has any objections, please let me know. ------------------ From: Chenguang Zhao [ Upstream commit 194762e6e436acde0f8f6aef44200b0058c36791 ] The responder CQE path determines the link layer via rdma_port_get_link_layer(). Use qp->port instead of hardcoding port 1, which can mis-decode completions on multi-port devices.
