*
* SkCsGetSendInfo - get checksum information for a send packet
*
* Description:
* Get all checksum information necessary to send a TCP or UDP packet. The
* function checks the IP header passed to it. If the high-level protocol
* is either TCP or UDP the pseudo header checksum is calculated and
* returned.
*
* The function returns the total length of the IP header (including any
* IP option fields), which is the same as the start offset of the IP data
* which in turn is the start offset of the TCP or UDP header.
*
* The function also returns the TCP or UDP pseudo header checksum, which
* should be used as the start value for the hardware checksum calculation.
* (Note that any actual pseudo header checksum can never calculate to
* zero.)
*
* Note:
* There is a bug in the GENESIS ASIC which may lead to wrong checksums.
*
* Arguments:
* pAc - A pointer to the adapter context struct.
*
* pIpHeader - Pointer to IP header. Must be at least the IP header *not*
* including any option fields, i.e. at least 20 bytes.
*
* Note: This pointer will be used to address 8-, 16-, and 32-bit
* variables with the respective alignment offsets relative to the pointer.
* Thus, the pointer should point to a 32-bit aligned address. If the
* target system cannot address 32-bit variables on non 32-bit aligned
* addresses, then the pointer *must* point to a 32-bit aligned address.
*
* pPacketInfo - A pointer to the packet information structure for this
* packet. Before calling this SkCsGetSendInfo(), the following field must
* be initialized:
*
* ProtocolFlags - Initialize with any combination of
* SKCS_PROTO_XXX bit flags. SkCsGetSendInfo() will only work on
* the protocols specified here. Any protocol(s) not specified
* here will be ignored.
*
* Note: Only one checksum can be calculated in hardware. Thus, if
* SKCS_PROTO_IP is specified in the 'ProtocolFlags',
* SkCsGetSendInfo() must calculate the IP header checksum in
* software. It might be a better idea to have the calling
* protocol stack calculate the IP header checksum.
*
* Returns: N/A
* On return, the following fields in 'pPacketInfo' may or may not have
* been filled with information, depending on the protocol(s) found in the
* packet:
*
* ProtocolFlags - Returns the SKCS_PROTO_XXX bit flags of the protocol(s)
* that were both requested by the caller and actually found in the packet.
* Protocol(s) not specified by the caller and/or not found in the packet
* will have their respective SKCS_PROTO_XXX bit flags reset.
*
* Note: For IP fragments, TCP and UDP packet information is ignored.
*
* IpHeaderLength - The total length in bytes of the complete IP header
* including any option fields is returned here. This is the start offset
* of the IP data, i.e. the TCP or UDP header if present.
*
* IpHeaderChecksum - If IP has been specified in the 'ProtocolFlags', the
* 16-bit Internet Checksum of the IP header is returned here. This value
* is to be stored into the packet's 'IP Header Checksum' field.
*
* PseudoHeaderChecksum - If this is a TCP or UDP packet and if TCP or UDP
* has been specified in the 'ProtocolFlags', the 16-bit Internet Checksum
* of the TCP or UDP pseudo header is returned here.

*
* SkCsGetReceiveInfo - verify checksum information for a received packet
*
* Description:
* Verify a received frame's checksum. The function returns a status code
* reflecting the result of the verification.
*
* Note:
* Before calling this function you have to verify that the frame is
* not padded and Checksum1 and Checksum2 are bigger than 1.
*
* Arguments:
* pAc - Pointer to adapter context struct.
*
* pIpHeader - Pointer to IP header. Must be at least the length in bytes
* of the received IP header including any option fields. For UDP packets,
* 8 additional bytes are needed to access the UDP checksum.
*
* Note: The actual length of the IP header is stored in the lower four
* bits of the first octet of the IP header as the number of 4-byte words,
* so it must be multiplied by four to get the length in bytes. Thus, the
* maximum IP header length is 15 * 4 = 60 bytes.
*
* Checksum1 - The first 16-bit Internet Checksum calculated by the
* hardware starting at the offset returned by SkCsSetReceiveFlags().
*
* Checksum2 - The second 16-bit Internet Checksum calculated by the
* hardware starting at the offset returned by SkCsSetReceiveFlags().
*
* Returns:
* SKCS_STATUS_UNKNOWN_IP_VERSION - Not an IP v4 frame.
* SKCS_STATUS_IP_CSUM_ERROR - IP checksum error.
* SKCS_STATUS_IP_CSUM_ERROR_TCP - IP checksum error in TCP frame.
* SKCS_STATUS_IP_CSUM_ERROR_UDP - IP checksum error in UDP frame
* SKCS_STATUS_IP_FRAGMENT - IP fragment (IP checksum ok).
* SKCS_STATUS_IP_CSUM_OK - IP checksum ok (not a TCP or UDP frame).
* SKCS_STATUS_TCP_CSUM_ERROR - TCP checksum error (IP checksum ok).
* SKCS_STATUS_UDP_CSUM_ERROR - UDP checksum error (IP checksum ok).
* SKCS_STATUS_TCP_CSUM_OK - IP and TCP checksum ok.
* SKCS_STATUS_UDP_CSUM_OK - IP and UDP checksum ok.
* SKCS_STATUS_IP_CSUM_OK_NO_UDP - IP checksum OK and no UDP checksum.
*
* Note: If SKCS_OVERWRITE_STATUS is defined, the SKCS_STATUS_XXX values
* returned here can be defined in some header file by the module using CSUM.
* In this way, the calling module can assign return values for its own needs,
* e.g. by assigning bit flags to the individual protocols.
