* scsi: bfa: document overflow of io_profile_start_timeArnd Bergmann2017-12-051-1/+2
| | | | | | | | | | | | | | | io_profile_start_time() gets read using do_gettimeofday() and passed down as a 32-bit value through multiple functions. This will overflow in y2038 or y2106, depending on whether it gets interpreted as unsigned in the end. This changes do_gettimeofday() to ktime_get_real_seconds() and pushes the point at which it overflows to where we actually assign it to the bfa_fcpim_del_itn_stats_s structure, with an appropriate comment.

Previously only a single queue per queue group was used. - Added function tag to BFI message header. Only used by FC BFI messages. Used to translate host tag to firmware tag. bfa_lpuid() is changed to bfa_fn_lpu() that encodes both PCI function and port ID in BFI message header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix iotag handling: 1) Update and check io tag for retry case. 2) Clearing upper 3 bits in io tag when an IO completes. The 3 upper bits in io tags are used for counting FCP exchange retry. Un-cleared bits will cause firmware to access invalid memory when the same io tag is used for an IO to a target that doesn't support FCP exchange retry. 3) Only check the effective bits when validating an iotag. Other minor fixes: 1) Added trace to get FC header type with assert of unhandled packet received. Ignore the type FC_TYPE_FC_FSS (FC_XS). 2) Fixed the adapter info display check - to check for fcmode flag even.
