The new QED firmware has 2 main purposes -
First, it contains fixes to various initializations and firmware
logic including:
- Corrects iSCSI fast retransmit when data digest is enabled.
- Stop draining packets when receiving several consecutive PFCs.
- Prevent possible assertion when consecutively opening/closing
many connections.
- Prevent possible asserton due to too long BDQ fetch time.
In addition, this firmware contains sufficient infrastructure on which
we'll add iWARP support in our drivers.

This new firmware for the qed* adapters fixes multiple issues:
- Prevent accidental drops in Tx-switching between VFs.
- Corrct VF cleanup for higher VFs.
- Better handling of RoCE error flows.
- MR registration/deregistration corrections.
- Prevent possible HW attention during offloaded TCP teardown.
- Corrections to iSCSI retransmit flows.
In addition, this firmware is a requirement for supporting the
QL41xxx series of adapters, as it contains the necessary init
and firmware logic for those.

This new firmware for the qed* adpaters fixes several issues:
- Better blocking of malicious VFs.
- After FLR, Tx-switching [internal routing] of packets might
be incorrect.
- Deletion of unicast MAC filters would sometime have side-effect
of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.
In addition, it would allow driver some new functionality, including:
- Allowing PF/VF driver compaitibility with old drivers [running
pre-8.10.5.0 firmware].
- Better debug facilities.

The new QED firmware contains several new additions;
As for bug-fixes, it fixes a couple of issues:
- Wrong classification of packets in 4-port devices.
- Anti-spoof interoperability with encapsulated packets.
- Tx-switching of encapsulated packets.
It also slightly improves Tx performance in several scenarios.
>From the driver's feature-set POV, this firmware would
allow us to add 2 major enhancements in the near future:
- It would allow us produce a register dump from the device,
as well as other debug-related information.
- It should be sufficient for our iscsi driver, which we [hopefully]
plan to push upstream soon.

This patch pushes the next firmware for the QED module.
This fixes numerous bugs, most notably:
- FLR flow isn't properly working.
- Chip might become unrespronsive after closing a vport.
- Chip gets stuck when transmitting packet with length > mtu.
It would also allow us to push future features such as:
- Vlan filter offload.
- Encapsulation offload.
- Single Root IOV support.
- Timesync.
- Non-L2 protocols.
>From L2 perspecitve, it's also note-worthy to state that it:
- Changes fastpath HSI - fastpath will be moved to into using
Jumbo-over-BD.
- Improves throughput on single connection traffic.
