====================
qed: Misc cleanups and fixes

Patches #1 and #2 revolve around register access performed by driver;
The first merely adds some debug, while the second does some fixing
of incorrect PTT usage as well as preventing issues similar to those
fixed by 6f437d43

 ("qed: Don't use attention PTT for configuring BW").

Patch #3 better configures HW for architecture where cacheline isn't 64B.

Patches #4-#8 all affect iSCSI related functionaility -
adding statistics information [both to driver & management firmware],
passing information on number of resources to qedi, and simplifying
the Out-of-order implementation in SW.
