Howdy. Just noticed this change to min RDMA packet size and I don't seem to
see it in any patch notes. Maybe I just skipped the one where this changed?
mmlsconfig verbsRdmaMinBytes
verbsRdmaMinBytes 16384
(in case someone thinks we changed it)
[root at proj-nsd01 ~]# mmlsconfig |grep verbs
verbsRdma enable
verbsRdma disable
verbsRdmasPerConnection 14
verbsRdmasPerNode 1024
verbsPorts mlx5_3/1
verbsPorts mlx4_0
verbsPorts mlx5_0
verbsPorts mlx5_0 mlx5_1
verbsPorts mlx4_1/1
verbsPorts mlx4_1/2
Oddly I also see this in config, though I've seen these kinds of things before.
mmdiag --config |grep verbsRdmaMinBytes
verbsRdmaMinBytes 8192
