- * 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.
