| | | | | | | | | | | | | | | | | | | | | | | | | Adapter Interface fixes and changes - Modify the macro field from lpfc_init_vpi_vpi to lpfc_init_vfi_vpi - Add the new CQE_CODE_RECEIVE_V1 CQE Code, add code in the driver to handle the new Code the same as the CQE_CODE_RECEIVE code except that there are two new checks for this code that will cause the driver to use the new V1 macros for rq_id and fcf_id. - Fix a bug in lpfc_prep_seq() where the size out of the first CQE was ONLY being used, even though multiple dmabufs make up the sequence, each have their own CQE with potentially different sizes. - Fix bug in lpfc_bsg_ct_unsol_event() where the ulpContext and ulpWord[3] fields of the XMIT_SEQUENCE64_CX IOCB were being calculated incorrectly. - Do physical to logical translation before indexing into the active XRI array. - Populate physical vpi in the iocb data structure. - Put the current accumulated total in each IOCB in the chain as we are walking thru then. The last IOCB in the chain should have the total length of the sequence.

Only detect an error if the error bit is set and the RN bit is NOT set. - If mailbox completion code is not success AND the mailbox status is success, then and only then will the driver overwrite the mailbox status. - When driver initializing device, if the device is on a PCIe bus, set PCI's "needs fundamental reset" bit so that EEH uses fundamental reset instead of hot reset for recovery. - Prevent driver from using new WWN when changed in firmware (until driver reload) - When HBA reports maximum SGE size > 0xffffffff (infinite), override with 0x80000000. - Fixed potential missed SLI4 device initialization failure conditions. - Added 100ms delay before driver action following IF_TYPE_2 function reset. - Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node. - Add a check for the CVL received flag in the fcf inuse routine to avoid unregistering the fcf if Devloss fires before Delay discover timer fires.
