It also adds support for new features of T5. It adds these in cxgb4, cxgb4vf, RDMA/cxgb4 and csiostor drivers. Chelsio's T5 asic moves the architecture into 40GbE speeds. T5 is a 10/40GbE controller with full offload support of a complete Unified Wire solution comprising NIC, Virtualization, TOE, iWARP RDMA and FCoE. T5 supports all the offload, virtualization and switching capabilities of the existing T4 and adds some new features. The patch series does basic intialization for T5 in each driver. The patch series implements a low latency Write Combining work request path in cxgb4 and RDMA/cxgb4 driver for T5. It supports new T5 feature DSGL in RDMA/cxgb4 driver which enables direct DMA by HW to memory region PBL arrays and fast register PBL arrays from host memory. It adds support for dumping T5 registers, T5's debugfs support and enables doorbell drop recovery only for T4 in cxgb4 driver. To facilitate addition of support in csiostor for future adapters, a new framework for adapter specific operations has been defined. Consequently, T4 and T5 specific operations are now separated into different files. One of the csiostor patches also includes common bug fixes. We are submitting changes in all the drivers for T5 in one series since there are common changes in cxgb4 driver which are required by all the ULDs and csiostor. This way we can avoid build failures, build dependencies and ensure smooth integration. We request to merge this patch series via David Miller's net-next tree. We are copying respective maintainers of all the drivers for reviewing the changes. Kindly let us know in case of any review comments. We have successfully carried out networking, virtualization, iWARP and storage related stress tests on this patch series.
