139 * SkCsGetSendInfo - get checksum information for a send packet
140 *
141 * Description:
142 * Get all checksum information necessary to send a TCP or UDP packet. The
143 * function checks the IP header passed to it. If the high-level protocol
144 * is either TCP or UDP the pseudo header checksum is calculated and
145 * returned.
146 *
147 * The function returns the total length of the IP header (including any
148 * IP option fields), which is the same as the start offset of the IP data
149 * which in turn is the start offset of the TCP or UDP header.
150 *
151 * The function also returns the TCP or UDP pseudo header checksum, which
152 * should be used as the start value for the hardware checksum calculation.
153 * (Note that any actual pseudo header checksum can never calculate to
154 * zero.)
155 *
156 * Note:
157 * There is a bug in the GENESIS ASIC which may lead to wrong checksums.
158 *
159 * Arguments:
160 * pAc - A pointer to the adapter context struct.
161 *
162 * pIpHeader - Pointer to IP header. Must be at least the IP header *not*
163 * including any option fields, i.e. at least 20 bytes.
164 *
165 * Note: This pointer will be used to address 8-, 16-, and 32-bit
166 * variables with the respective alignment offsets relative to the pointer.
167 * Thus, the pointer should point to a 32-bit aligned address. If the
168 * target system cannot address 32-bit variables on non 32-bit aligned
169 * addresses, then the pointer *must* point to a 32-bit aligned address.
170 *
171 * pPacketInfo - A pointer to the packet information structure for this
172 * packet. Before calling this SkCsGetSendInfo(), the following field must
173 * be initialized:
174 *
175 * ProtocolFlags - Initialize with any combination of
176 * SKCS_PROTO_XXX bit flags. SkCsGetSendInfo() will only work on
177 * the protocols specified here. Any protocol(s) not specified
178 * here will be ignored.
179 *
180 * Note: Only one checksum can be calculated in hardware. Thus, if
181 * SKCS_PROTO_IP is specified in the 'ProtocolFlags',
182 * SkCsGetSendInfo() must calculate the IP header checksum in
183 * software. It might be a better idea to have the calling
184 * protocol stack calculate the IP header checksum.
185 *
186 * Returns: N/A
187 * On return, the following fields in 'pPacketInfo' may or may not have
188 * been filled with information, depending on the protocol(s) found in the
189 * packet:
190 *
191 * ProtocolFlags - Returns the SKCS_PROTO_XXX bit flags of the protocol(s)
192 * that were both requested by the caller and actually found in the packet.
193 * Protocol(s) not specified by the caller and/or not found in the packet
194 * will have their respective SKCS_PROTO_XXX bit flags reset.
195 *
196 * Note: For IP fragments, TCP and UDP packet information is ignored.
197 *
198 * IpHeaderLength - The total length in bytes of the complete IP header
199 * including any option fields is returned here. This is the start offset
200 * of the IP data, i.e. the TCP or UDP header if present.
201 *
202 * IpHeaderChecksum - If IP has been specified in the 'ProtocolFlags', the
203 * 16-bit Internet Checksum of the IP header is returned here. This value
204 * is to be stored into the packet's 'IP Header Checksum' field.
205 *
206 * PseudoHeaderChecksum - If this is a TCP or UDP packet and if TCP or UDP
207 * has been specified in the 'ProtocolFlags', the 16-bit Internet Checksum
208 * of the TCP or UDP pseudo header is returned here.

396 *
397 * Note:
398 * Before calling this function you have to verify that the frame is

401 * Arguments:
402 * pAc - Pointer to adapter context struct.
403 *
404 * pIpHeader - Pointer to IP header. Must be at least the length in bytes
405 * of the received IP header including any option fields. For UDP packets,
406 * 8 additional bytes are needed to access the UDP checksum.
407 *
408 * Note: The actual length of the IP header is stored in the lower four
409 * bits of the first octet of the IP header as the number of 4-byte words,
410 * so it must be multiplied by four to get the length in bytes. Thus, the
411 * maximum IP header length is 15 * 4 = 60 bytes.
412 *
413 * Checksum1 - The first 16-bit Internet Checksum calculated by the
414 * hardware starting at the offset returned by SkCsSetReceiveFlags().
415 *
416 * Checksum2 - The second 16-bit Internet Checksum calculated by the
417 * hardware starting at the offset returned by SkCsSetReceiveFlags().
418 *
419 * Returns:
420 * SKCS_STATUS_UNKNOWN_IP_VERSION - Not an IP v4 frame.
421 * SKCS_STATUS_IP_CSUM_ERROR - IP checksum error.
422 * SKCS_STATUS_IP_CSUM_ERROR_TCP - IP checksum error in TCP frame.
423 * SKCS_STATUS_IP_CSUM_ERROR_UDP - IP checksum error in UDP frame
424 * SKCS_STATUS_IP_FRAGMENT - IP fragment (IP checksum ok).
425 * SKCS_STATUS_IP_CSUM_OK - IP checksum ok (not a TCP or UDP frame).
426 * SKCS_STATUS_TCP_CSUM_ERROR - TCP checksum error (IP checksum ok).
427 * SKCS_STATUS_UDP_CSUM_ERROR - UDP checksum error (IP checksum ok).

429 * SKCS_STATUS_UDP_CSUM_OK - IP and UDP checksum ok.
430 * SKCS_STATUS_IP_CSUM_OK_NO_UDP - IP checksum OK and no UDP checksum.
431 *
432 * Note: If SKCS_OVERWRITE_STATUS is defined, the SKCS_STATUS_XXX values
