Firmware ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2.1. T5 Firmware ++++++++++++++++ Version : 1.15.28.0 Date : 02/29/2016 ================================================================================ FIXES ----- BASE: - Fixed an issue in FW_RSS_VI_CONFIG_CMD handling where the default ingress queue was ignored. - Fixed an issue where adapter failed to load fw by adjusting DRAM frequency. - Fixed an issue in watchdog which was causing VM bring-up failure after reboot. - Fixed 40G link failures with some switches when auto-negotiation enabled. - Fixed to improve on link bring-up time. - Per port buffer groups size doubled to improve performance. - Fixed an issue where bogus d3hot bits were set causing traffic stall. - Fixed an issue where sometimes adapter was not seen after reboot. - Fixed an issue where iWARP was crashing in conjunction with traffic management. - Fixed an issue where link failed to come up after removing twinax cable and inserting optical module. OFLD - Fixed a potential iSCSI data corruption issue by disabling RxFragEn flag. FOiSCSI - Fixed an issue in recovery path where connection was getting closed before recovery processing was done. - Fixed an issue in TCP port reuse. - Fixed an issue in recovery path when large number (>64) of iSCSI connections were in use. - Returned ENETUNREACH if IP was not been provisioned yet and driver tried to use given inerface. ENHANCEMENTS ------------ BASE: - Added new interface to program DCA settings in SGE contexts; allow 32-byte IQE size - Added PTP interface fw_ptp_ts to support PTP Frequeny and Offset adjustment. - Added MPS raw interface. ETH: - New mailbox command FW_DCB_IEEE_CMD api added for IEEE dcbx. OFLD: - WR opcode is returned to host in cqe error response. 2.2.
