1. Several corner case bugs in iSCSI code.
2. Fixes for FCoE including support for 3PAR targets.
3. Fixes for SR-IOV behaviour including:
a. Remove FW assert erroneously triggered during FLR.
b. Several fixes in FLR flow.
c. Prevent VF crash when packet bigger than MTU arrives.
d. Improve security against malicious VF.
4. Added CSUM and TSO support for encapsulation protocols.
5. Added RSS capability for GRE traffic based on inner headers.
6. Added FCoE support for 4-port 57840 devices.

This new firmware fixes several minor bugs:
1. In switch dependent mode, DCB priority was used to override inner vlan
priority.
2. In switch dependent mode, inner vlan was added in case of DCB priority
even if outer vlan was present.
3. In switch dependent mode, outer vlan was overridden by DCB priority when
working in STATIC COS mode while inner vlan was present.
4. iSCSI - under heavy iSCSI traffic, when TCP out-of-order condition
occurred, it was possible for the connection to close and recover.
5. iSCSI - connections on-chip TCP establishment might have failed.
6. iSCSI - out-of-order isles might have caused on-chip TCP connections
to fail in their graceful termination.
7. iSCSI - there was a theoretical race in which an RST packet sent from
pure-ack queue in specific timing could cause a credit-return overflow.
8. iSCSI - not all packets were completed on a forward channel.
9. DCB - fixed for 4-port devices; Until now, wrong credit counters were
used, causing dcb to fail.
10. Fixed false parity reported in CAM memories when operating near -5% on
the 1.0V core supply.
11. ETS default settings are set to fairness between traffic classes (rather
than strict priority), and uses the same chip receive buffer configuration
for both PFC and pause.

This new FW adds support in AFEX mode (multifunction using vntag
header).
It also fixes following issues:
1. Theoretical bug in GRO acceleration (only if the GRO Segment Length
is a multiple of the SGE Size). This will allow removing the
workaround from the driver.
2. When a TPA aggregation is open and a packet is accepted with
timestamp OOO, the new packet begins a new aggregation instead of
being indicated separately.

This new FW adds the ability to aggregate packets for GRO (and not just LRO) and
also fixes some bugs. Please consider adding it to the FW tree:
1. Added new aggregation mode: GRO. In this mode packets are aggregated such
that the original packets can be reconstructed by the O/S.
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.

This is the new FW HSI blob and the relevant definitions without logic changes.
It also included code adaptation for new HSI. New features are not enabled.
New FW/HSI includes:
- Support for 57712 HW
- Future support for VF (not used)
- Improvements in FW interrupts scheme
- FW FCoE hooks (stubs for future usage)

Includes fixes for the following issues:
1. (iSCSI) Arrival of un-solicited ASYNC message causes
firmware to abort the connection with RST.
2. (FCoE) There is a probability that truncated FCoE packet on
RX path won't get detected which might lead to FW assert.
3. (iSCSI) Arrival of target-initiated NOP-IN during intense
ISCSI traffic might lead to FW assert.
4. (iSCSI) Chip hangs when in case of retransmission not aligned
to 4-bytes from the beginning of iSCSI PDU.
5. (FCoE) Arrival of packets beyond task IO size can lead to crash.
