| 3 | References: bnc #465596 | |
| 4 | ||
| 5 | When a rport goes away, libFC does a plogi which will reset exchanges | |
| 6 | at the rport. Clean exchanges at our end, both in transport and libFC. | |
| 7 | If transport hooks into exch_mgr_reset, it will call back into | |
| 8 | fc_exch_mgr_reset() to clean up libFC exchanges. | |
