PBL chain elements are actually DMA addresses stored in __le64, but
currently their size is hardcoded to 8, and DMA addresses are assigned
via cast to variable-sized dma_addr_t without any bitwise conversions.

assignment.

net: qed: sanitize BE/LE data processing

Current code assumes that both host and device operates in Little Endian
in lots of places. While this is true for x86 platform, this doesn't mean
we should not care about this.

This commit addresses all parts of the code that were pointed out by sparse
checker. All operations with restricted (__be*/__le*) types are now
protected with explicit from/to CPU conversions, even if they're noops on
common setups.

I'm sure there are more such places, but this implies a deeper code
investigation, and is a subject for future works.

qed*: Refactor mf_mode to consist of bits.

`mf_mode' field indicates the multi-partitioning mode the device is

requires going over all the existing conditions, and deciding whether those
are needed for the new mode or not.
The patch defines a set of bit-fields for modes which are derived according
to the mode info shared by the MFW and all the configuration would be made
according to those. To add a new mode, there would be a single place where
we'll need to go and choose which bits apply and which don't.

This pushes qed [and as result, all qed* drivers] into using 8.20.0.0

Content-wise, the firmware contains fixes to various issues exposed
since the release of the previous firmware, 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 assertion due to too long BDQ fetch time.

In addition, the new firmware would allow us to later add iWARP support
in qed and qedr.
