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. Signed-off-by: Bin Meng <bin.meng@windriver.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
