Subject: [RDMA RFC v6 00/16] Intel RDMA Driver Updates 2020-05-19 

This patch set adds a unified Intel Ethernet Protocol Driver for RDMA that
supports a new network device E810 (iWARP and RoCEv2 capable) and the
existing X722 iWARP device. The driver architecture provides the extensibility
for future generations of Intel HW supporting RDMA.

This driver replaces the legacy X722 driver i40iw and extends the ABI already
defined for i40iw. It is backward compatible with legacy X722 rdma-core
provider (libi40iw).

This series was built against the rdma for-next branch.  This series is
dependant upon the v4 100GbE Intel Wired LAN Driver Updates 2020-05-19
12 patch series, which adds virtual_bus interface and ice/i40e LAN
driver changes.

v5-->v6:
*Convert irdma destroy QP to a synchronous API 
*Drop HMC obj macros for use counts like IRDMA_INC_SD_REFCNT et al.
*cleanup unneccesary 'mem' variable in irdma_create_qp 
*cleanup unused headers such as linux/moduleparam.h et. al 
*set kernel_ver in irdma_ualloc_resp struct to current ABI ver. Placeholder to
 support user-space compatbility checks in future 
*GENMASK/FIELD_PREP scheme to set WQE descriptor fields considered for irdma
 driver but decision to drop. The FIELD_PREP macro cannot be used on the device
 bitfield mask array maintained for common WQE descriptors and initialized
 based on HW generation. The macro expects compile time constants only.
*Use irdma_dbg macro in driver callsites for debug. This macro will use
 ibdev_dbg or dev_dbg depending on ibdevice allocated or not. Other print
 callsites reviewed to use ibdev_* macros wherever possible.
*module alias for i40iw moved to Patch #15 where i40iw driver is removed.
*Misc. driver fixes

v4-->v5:
*Drop driver_data usage from virtbus device id. Use string id match to identify
 virtbus device type.
*Rename device discovery functions
*Drop rdma_set_device_sysfs_group API usage *READ_ONCE annotations for netdev
 flags in rcu_read_lock 

v4:
*Remove redundant explicit casts
*Scrub all WQs to define correct charateristics and use system WQ for reset
 recovery work *Remove all non-functional NULL checks on IDC peer dev OPs 
*Change all pr_* to dev_* if struct device present. Remove dev_info logging 
*Don't use test_bit on non-atomic IIDC_* event types *Remove all module 
 parameters 
*Use bool bitfields in structures instead of bool 
*Change CQP completion handling from kthread to WQ 
*Use the generic devlink parameter enable_roce instead of driver specific one 
*Use meaningful labels for goto unwind *Use new RDMA mmap API 
*Use refcount_t APIs for refcounts on driver objects 
*Add support for ibdev OP dealloc_driver 
*Adapt to use new version of virtbus 
*Remove RCU locking in CM address resolve *Misc. driver fixes
