Re: [dpdk-dev] [v2] telemetry: fix json output buffer size

Hi Ciara,

I am not sure about why we would want this to allow for
"RTE_TEL_MAX_SINGLE_STRING_LEN - 6".
The RTE_TEL_MAX_SINGLE_STRING_LEN is used to represent the max size of a
singular string value e.g. the response to client being   {"<cmd>" : "<string value
here up to max size in length>" }

I wonder could we use the "len" parameter in some way here, that would be the
available space to be filled of the "buf" being passed in, allowing the function to
copy in the maximum amount to fill the buffer.

Got it. Yeah, "len" is actual available space. I ll send next version based on this.

Also, I propose if we can have platform defined upper limits (esp MAX_CMD_LEN,
MAX_SINGLE_STRING_LEN etc) so that, we need not revisit lib/telemetry for
platform needs (and I don't think one size fits all platform, may be excess too).
Thoughts ?
