[PATCH 4/5] app/proc-info: show RSS types with strings

[Dongdong Liu <liudongdong3@huawei.com>]

From: Jie Hai <haijie1@huawei.com>

show RSS types details and adjust RSS info display format as following:

  - RSS info
	  -- hf:
		ipv4  ipv4-frag  ipv4-other  ipv6  ipv6-frag  ipv6-other
	  -- key len: 40
	  -- key (hex): 6d5a56da255b0ec24167253d43a38fb0d0ca2bcbae7b30b477cb2da38030f20c6a42b73bbeac01fa
