The variable cache_allocs is to indicate how many frags (KiB) are in one
rds connection frag cache.
The command "rds-info -Iv" will output the rds connection cache
statistics as below:
"
RDS IB Connections:
LocalAddr RemoteAddr Tos SL LocalDev RemoteDev
1.1.1.14 1.1.1.14 58 255 fe80::2:c903:a:7a31 fe80::2:c903:a:7a31
send_wr=256, recv_wr=1024, send_sge=8, rdma_mr_max=4096,
rdma_mr_size=257, cache_allocs=12
"
This means that there are about 12KiB frag in this rds connection frag
cache.

Some of this header file changes, how is taking care of backward
compatibility with tooling ? This was one of the reason, the
all the fields are not updated.
