net: checksum: Introduce fine control over checksum type
At present net_checksum_calculate() blindly calculates all types of
checksums (IP, TCP, UDP). Some NICs may have a per type setting in
their BDs to control what checksum should be offloaded. To support
such hardware behavior, introduce a 'csum_flag' parameter to the
net_checksum_calculate() API to allow fine control over what type
checksum is calculated.
Existing users of this API are updated accordingly.
