Browse Source 
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

* Name: ipv6_chksum

* Description:
* Calculate the IPv6 header checksum of the packet header in d_buf.
*
* The IPv6 header checksum is the Internet checksum of the 40 bytes of
* the IPv6 header.
*
* If CONFIG_NET_ARCH_CHKSUM is defined, then this function must be
* provided by architecture-specific logic.
*
* Returned Value:
* The IPv6 header checksum of the IPv6 header in the d_buf buffer.
