IIO Bandwidth Counter
Free running counter that increments on each AD request sent to the ring. Pcode
uses this for power metering and also for uncore P state related decisions. Pcode
can clear this counter by writing a 1 to all bits in this field, at which time the
counter starts from 0.

1RW-LB0b
Intel QPI Routing Table Select for NDR/DRS packets
When this bit is set, R2PCIe routes NDR and DRS packets destined to remote
sockets, using the QPI_RT. When this bit is clear, R2PCIe routes NDR and DRS
packets destined to remote sockets, using the Intel QPI Link_ID field sent by IIO/
Ubox along with these packet.
0RWS-LB0b
Extended RTID Mode Enable
When this bit is set, R2PCIe ignores DNID[2] on DRS packets (on BL ring). For
NDR packets on AK ring, all the NDR packets always go to local targets only and
hence this change is not needed) when determining if a packet is targeted at a
local or remote target.
