commit 08c6f62256c05acc21751237f0d45c611e097ad0
Author: Xiang Xiao <xiaoxi...@xiaomi.com>
AuthorDate: Thu Jan 30 15:45:15 2020 +0800
Fix net checksum related issue
1.Remove the unused and unimplemented ipv6_chksum declaration
2.Update NET_ARCH_CHKSUM description to align with the implementation
3.Declare all checksum function prototype regardless CONFIG_NET_ARCH_CHKSUM
4.Remove the CONFIG_NET_ARCH_CHKSUM guard for tcp_ipv[4|6]_chksum
