UCX_RC_VERBS_TX_MAX_CHUNK_SIZE

[w7658610]

UCX_RC_VERBS_TX_MAX_CHUNK_SIZE=128M，
Does this mean that when large packets are sent, they are split into multiple 128MB?

And mpool have chunks, and chunk have elements,But what are in elements?
Data is first split into chunks and then into elements？

Thanks.
