net: rds: add per rds connection cache statistics
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. Since rds.h in rds-tools is not related with the kernel rds.h, the change in kernel rds.h does not affect rds-tools. rds-info in rds-tools 2.0.5 and 2.0.6 is tested with this commit. It works well.
