[v5,38/40] app/proc-info: adjust the display format of RSS info
Checks
Commit Message
This patch splits the length and value of RSS key into two parts,
removes spaces between RSS keys, and adds line breaks between RSS
key and RSS hf.
Before the adjustment, RSS info is shown as:
- RSS
-- RSS len 40 key (hex): 6d 5a 56 da 25 5b e c2 41 67 \
25 3d 43 a3 8f b0 d0 ca 2b cb ae 7b 30 b4 77 cb 2d \
a3 80 30 f2 c 6a 42 b7 3b be ac 1 fa -- hf 0x0
and after:
- RSS info
-- key len : 40
-- key (hex) : 6d5a56da255b0ec24167253d43a38fb0d0c \
a2bcbae7b30b477cb2da38030f20c6a42b73bbeac01fa
-- hash function : 0x0

How about convert to string? e.g. hash function: SIMPLE_XOR

Sorry for the misunderstanding.
"hash function" is for rss_hf, not the RSS hash algorithm.

"hash function" is for rss_hf, not the RSS hash algorithm.
And each bit of it is meaningful, so hexadecimal is used.
