IPoIB UD uses SRQ by nature (since RX from all peers consume buffers
from the --only-- RQ) and lives fine with 32 buffers (or 64 you can look
in the code). Moreover, my assumption is that
pps(RC) <= pps(UC) <= pps(UD)
this means that what ever number of RX buffer for UD/2K MTU which is
"enough" to have no (or close to zero) packet loss under some traffic
pattern, the same pattern can be served with IPoIB CM using SRQ of the
same size.
Or.
