Subject: netinet/tcp.h: add tcp_info fields from linux v4.19
X-Git-Tag: v1.1.22~33
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=b47723ab3b61d7840b08c56375e35546f7b4a8a9;p=oweals%2Fmusl.git

netinet/tcp.h: add tcp_info fields from linux v4.19

new fields for RFC 4898 tcp stats in linux
tcpi_bytes_sent added in commit ba113c3aa79a7f941ac162d05a3620bdc985c58d
tcpi_bytes_retrans added in commit fb31c9b9f6c85b1bad569ecedbde78d9e37cd87b
tcpi_dsack_dups added in commit 7e10b6554ff2ce7f86d5d3eec3af5db8db482caa
tcpi_reord_seen added in commit 7ec65372ca534217b53fd208500cf7aac223a383

The new fields change the size of a public struct and thus an ABI break,
but this is how the getsockopt TCP_INFO api is designed: the tcp_info
type must only be used with a length parameter in extern interfaces.
