use FW 7.2.16
The patch integrates FW 7.2.16 HSI and implements driver
part of GRO flow.
FW 7.2.16 adds the ability to aggregate packets for GRO
(and not just LRO) and also fixes some bugs.
1. Added new aggregation mode: GRO. In this mode packets are aggregated
such that the original packets can be reconstructed by the OS.
2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32.
3. Adding the FCoE statistics structures to the BNX2X HSI.
4. Wrong configuration of TX HW input buffer size may cause theoretical
performance effect. Performed configuration fix.
5. FCOE - Arrival of packets beyond task IO size can lead to crash.
Fix firmware data-in flow.
6. iSCSI - In rare cases of on-chip termination the graceful termination
timer hangs, and the termination doesn't complete. Firmware fix to MSL
timer tolerance.
7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles
open at the initiator side. Firmware implementation corrected to drop
FIN received out-of-order or with isles still open.
8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes
from the beginning of iSCSI PDU. Firmware implementation corrected
to support arbitrary aligned retransmissions.
9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic
might lead to crash. Firmware fix to relevant flow.
