RDMA/cxgb4: Add DB Overflow Avoidance
Get FULL/EMPTY/DROP events from LLD. On FULL event, disable normal
user mode DB rings.
Add modify_qp semantics to allow user processes to call into the
kernel to ring doobells without overflowing.
Add DB Full/Empty/Drop stats.
Mark queues when created indicating the doorbell state.
If we're in the middle of db overflow avoidance, then newly created
queues should start out in this mode.
Bump the C4IW_UVERBS_ABI_VERSION to 2 so the user mode library can
know if the driver supports the kernel mode db ringing.
