Andrew, Does ISP2432 support ABORT_TASK_SET and CLEAR_TASK_SET TMFs ? I understand that Linux SCSI EH strategy doesnt make use of these TMFs so QLA2xxx driver doesn't have code related to these. But If I want to extend the QLA driver to support these TMFs using following mailbox commands: MBC_ABORT_TASK_SET MBC_CLEAR_TASK_SET so that I can invoke them thru some IOCTL based appln... a) would ISP 2432 firmware/asic support these TMFs ? Are there any known gotchas that one should be careful about while implementing these? b) While coding the handler for these TMFs which existing EH routine would u recommend to be used as template/reference ? c) Since current/latest driver doesnt have any code for these TMFs, what is the exact mailbox command format for these TMFs ? thanks, tkrishna - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
