[SCSI] lpfc 8.2.8 v2 : Add statistical reporting control and additional fc vendor events
Added support for new sysfs attributes: lpfc_stat_data_ctrl and lpfc_max_scsicmpl_time. The attributes control statistical reporting of io load. Added support for new fc vendor events for error reporting. Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
