| 268 | * Description: |
| 269 | * This routine dumps the host buffer queue info from the @phba to @buf up to |
| 270 | * @size number of bytes. A header that describes the current hbq state will be |
| 271 | * dumped to @buf first and then info on each hbq entry will be dumped to @buf |
| 272 | * until @size bytes have been dumped or all the hbq info has been dumped. |
| 273 | * |
| 274 | * Notes: |
| 275 | * This routine will rotate through each configured HBQ each time called. |
| 276 | * |
| 277 | * Return Value: |
| 278 | * This routine returns the amount of bytes that were dumped into @buf and will |
| 279 | * not exceed @size. |

James Smart | e59058c | 2008-08-24 21:49:00 -0400 | [diff] [blame] | 530 | * @vport: The vport to gather target node info from. |
| 531 | * @buf: The buffer to dump log into. |
| 532 | * @size: The maximum amount of data to process. |
| 533 | * |
| 534 | * Description: |
| 535 | * This routine dumps the current target node list associated with @vport to |
| 536 | * @buf up to @size bytes of data. Each node entry in the dump will contain a |
| 537 | * node state, DID, WWPN, WWNN, RPI, flags, type, and other useful fields. |
| 538 | * |
| 539 | * Return Value: |
| 540 | * This routine returns the amount of bytes that were dumped into @buf and will |
| 541 | * not exceed @size. |
